Trueforce For All

The ultimate companion for a Trueforce-enabled Logitech wheel. Trueforce haptics in any game, rev light enhancements, the Dynamic OLED screen, a phone dash, and community presets.

Latest release Downloads Windows License Discord

Download the latest release

Free and open source, for SimHub. Contributors welcome.

Official Trueforce support keeps growing, but many major titles are still waiting and some will never get it. This plugin fills the gap, and then some.

[!TIP] Something not working? Please open an issue or say so in the Discord.

Supported wheels

Wheel Haptics + FFB Rev lights OLED screen
Logitech G PRO Racing Wheel (Xbox/PC and PS/PC) ✅ ✅ ✅
Logitech RS50 ✅ ✅ ✅
Logitech G923 (Xbox/PC and PS/PC) ✅ ✅ None

[!NOTE] The plugin can add rev light support and control the Dynamic OLED screen in games with Telemetry Based FFB, in iRacing, RaceRoom and Le Mans Ultimate, and in Assetto Corsa with the CSP Bridge. LIGHTSYNC car pattern matching works in every game the pattern data covers.

FFB and Trueforce Effects

The plugin layers Trueforce haptics over the game’s built-in FFB. In most games it reads the force off the wire and adds to it.

Some games go further. iRacing, RaceRoom, Le Mans Ultimate and Assetto Corsa hand their force straight to the plugin, with no USB capture involved. In the Forza titles and Farming Simulator, Telemetry Based FFB can build the whole force instead. In these games the wheel’s rev lights and screen are unlocked too, and Per-game enhancements covers what each one gets.

Save your tunings per game and per car, and use the preset browser to manage your presets and share with the community.

Effects from telemetry

Synthesized from live game data and played over the Trueforce protocol.

  • Engine pulse: rumble at the engine’s real firing pattern, from its cylinder count and crank layout, so a cross-plane V8 does not feel like an inline six.
  • Gear shift: a short low-frequency thud whenever the gear changes.
  • ABS click: configurable haptic when ABS engages.
  • Pit limiter: configurable pulsing buzz while the limiter is engaged.
  • Redline buzz: a hard buzz when you enter the redline. On by default.
  • DRS: a chirp as the wing opens, and an optional flutter while it stays open.
  • Road bumps: rough ground rumbles through the wheel, read per tire in Forza for a sharper surface.
  • Curb thump: the whack as a wheel first meets a curb, separate from the rumble that follows while you ride it.
  • Implement thud: the hydraulic hum as an implement or loader arm moves, and the thump as it lands. (Farming Simulator.)
  • Traction loss: tire screech when grip breaks, sharpest where the game reports per-wheel slip.
  • Axle slip: understeer and oversteer as two feelings rather than one blur, a high scrub as the front washes wide, a deeper pulse as the rear steps out.
  • Lockup judder: the coarse judder of a flat-spotted tire skidding under braking, fading as the car slows.
  • Collision: a thud on impact, scaled to the hit.
  • Airborne ducking: the effects you choose cut out while the car is in the air, so jumps feel weightless. On by default.
  • Stationary spring: weight at the wheel when parked or crawling, fading out as speed builds.

Which effects a game can drive depends on the telemetry it publishes, so the plugin shows the ones your game supports and hides the rest.

Effects from game audio

The game’s own audio, captured from its process and fed to the wheel as haptics. It catches what telemetry never exposes, and works in games that publish none at all.

Trueforce EQ

A parametric equalizer on the plugin’s Trueforce effects. Cut the frequencies where your rig rattles and boost any that feel weak.

Telemetry Based FFB

In supported games the plugin builds the entire steering force itself, instead of passing the game’s own force feedback through. Today that means the Forza titles (Forza Motorsport and Forza Horizon 4, 5, and 6) and Farming Simulator 22 and 25.

It also unlocks the wheel’s rev lights and screen, with the lights filling and flashing with the engine.

FFB spike reduction

Some games (Assetto Corsa being the worst offender we’ve seen) deliver curb and collision FFB spikes wildly out of proportion to what’s safe or comfortable. On a strong wheelbase they can ruin a racing line or cause real wrist strain over a session. iRacing has a built-in softener; most other games don’t. The plugin attenuates spikes only, so curbs land as confident pushes instead of yanks while sustained cornering load and weight transfer pass through untouched. Useful on its own, even with all our other effects turned off.

Per-game enhancements

Some games get enhancements of their own, whether that is a faster telemetry stream, sharper effects, a force feedback overhaul, or the sim handing its forces straight to the plugin. None of it needs a SimHub license.

iRacing

iRacing keeps publishing the steering torque it wants the wheel to hold even with its own force feedback off, so the plugin carries that to the wheel with its effects on top, and the rev lights and the wheel’s screen come with it.

  • Each car’s max force, learned. The plugin watches what a car really pushes; drive a clean lap, and once the reading holds steady, one press takes it. Nudge any car heavier or lighter from there.
  • Curb strikes and rumble strips, softened. iRacing reports each wheel’s suspension speed beside the torque, so only the instants a curb lands are eased; cornering load and weight transfer pass through untouched. On by default, with a slider for how much to take out.
  • A stop where the car’s steering stops. A soft lock built from the sim’s own steering position and lock, so the wheel no longer turns on past the car’s lock to its hard stop. On by default.
  • Incident points, announced. The dash shows your count against the session’s limit, and the wheel’s screen flashes what each new one cost.
  • Engines sound like themselves. iRacing states each car’s cylinder count, and a shipped table adds the crank layout, so a cross-plane V8 pulses like one.

Setup instructions show in the plugin on first launch, or here.

Assetto Corsa

Shared memory read at the game’s own 333 Hz physics rate, which makes curb collisions, road bumps and traction loss noticeably sharper than a 60 Hz feed can deliver.

  • The TF4ALL CSP Bridge hands the force over. A small CSP script the plugin offers to install, after which your rev lights and the wheel’s screen run, light patterns can be changed mid-session, and Assetto Corsa needs no USB capture at all.

Setup instructions show in the plugin when it first sees the game, or here.

RaceRoom

Telemetry read from the game’s shared memory, far above SimHub’s 60 Hz max, carries the steering force RaceRoom computes to the wheel with the plugin’s effects on top, and the rev lights and the wheel’s screen come with it.

  • Each car’s strength, learned. Drive a couple of clean laps, and once the reading holds steady one press takes it.
  • Engine data for every car in the game. A shipped table covers all 356 with their real cylinder count and crank layout, so a V8 pulses like one.

Setup instructions show in the plugin when it first sees the game, or here.

Le Mans Ultimate

The official shared memory its SDK documents, read at 100 Hz, carries the torque on the steering shaft to the wheel with the effects on top, and the rev lights and the wheel’s screen come with it.

  • Each car’s peak force in Nm, learned, and taken with one press, the same gesture iRacing uses.

Setup instructions show in the plugin when it first sees the game, or here.

Forza

Telemetry read straight from the game over UDP, output at the game’s frame rate, which is often much higher than SimHub’s 60 Hz cap.

  • Per-tire data. SimHub leaves this out, so reading it from the game directly is what lets us enhance the surface texture effect, curb strikes and collisions.
  • Telemetry Based FFB, which can replace Forza’s own force feedback outright.
  • SimHub still gets its copy, so dashboards and bass shakers keep working.

Setup instructions show in the plugin when it first sees the game, or here and here.

Farming Simulator

Force feedback in Farming Simulator is notoriously basic. The game gives the wheel a centering spring and little else, so Telemetry Based FFB replaces it with a force of its own, built from the ground under the tires, the weight of the machine as it turns and an implement dragging harder as it fills.

  • The TF4ALL Enhanced Telemetry mod comes with it, adding ground texture through the wheel, the thud as an implement drops into work, and the cut while your wheels are off the ground. The game publishes too little on its own, so the mod sends it, at up to 100 Hz.
  • Baked-in engine data for all 153 Farming Simulator 25 base-game vehicles, so the engine effects know what they are driving without being told.

Setup instructions show in the plugin when it first sees the game, or here.

Every other SimHub-supported game runs through SimHub’s universal telemetry feed instead. The plugin works there without a SimHub license, but unlicensed that feed is capped at 10 Hz, which makes the effects feel coarse. A licensed copy of SimHub (a small one-time payment) lifts it to 60 Hz, a big step up in feel.

The wheel’s lights

The LIGHTSYNC tab takes over the rev strip on a G PRO or RS50. The G923’s strip has a fixed layout, so the tab stays hidden there.

  • The pattern can match the car you are driving. The strip takes on each car’s own colors and fill direction as you get in, lighting where the real car lights. The data comes from Lovely Sim Racing (CC BY-NC-SA 4.0); a car they have not covered keeps the pattern you chose.
  • Save as many patterns as you want. The wheel stores five; the plugin’s library has no limit, and a bound button walks it without taking your hands off the wheel.
  • A pattern maker. Color the ten LEDs one at a time, with the wheel showing the whole pattern as you work. Thirteen hand-made patterns come built in, yours to copy and edit.
  • Color trim, pre-tuned. The three colors inside an LED are not equally bright, so an even mix of red and green can reach the rim looking lime. Three sliders correct the balance, shipped already set from measurements on a G PRO.
  • A car can remember its own. One click on “Remember for this car” and the pattern comes back whenever that car loads.
  • Idle modes. With no game running, or the car sat still, the strip can run a slow sweep up and back, or meter your computer’s audio so the lights move with whatever you are listening to. Your revs take the lights back the moment a game reports them. Off by default.
  • The TF4ALL Dash’s rev strip can match the wheel’s, colors, fill direction and switch-on points included.

Picks apply immediately, in and out of game. In a game whose force feedback passes through the USB capture, changing the pattern interrupts that force for a moment, so it is best done parked.

Three modes, remembered per game. Normal (everything), Lightsync only (the plugin leaves the game’s force feedback and Trueforce alone and only sets the light pattern for the car you are in), or Off. Games that bring their own Trueforce start on Lightsync only.

The wheel’s OLED screen

The G PRO and RS50 have a small display in the middle of the wheel. The plugin takes it over, and you choose what goes on it.

  • Eleven ready-made screens. Speed over gear and gear over speed, captioned or not; speed alone or gear alone; a big gear with the speed beside it, and the reverse; and three that carry your lap delta. Or pick Nothing and keep the wheel’s own display, with shifts, finished laps and warnings still taking the screen for a moment.
  • Or build your own. Pick a layout, then choose what goes in each slot: gear, speed, lap delta, position, lap of total, last lap time, or your own text. The editor gives each slot’s size and character limit, and shows the screen on the wheel as you build it.
  • It reacts as you drive. Shift and it flashes the gear, unless your screen already shows it. Cross the line and it puts up the lap time with your delta underneath, and tells you when it was a personal best.
  • It reports changes as they happen, like a preset loading or a gain you just nudged, and warns you if the game is still sending its own force feedback.

Bind a button to step through your screens without letting go of the wheel.

TF4ALL Dash

The plugin ships its own SimHub dashboard, made for a phone or tablet kept next to you or mounted on the rig: what you need at a glance while you drive, and a way to change things mid-session without alt-tabbing out of the game.

  • The Drive tab: a big gear and rev strip, plus four info boxes you can set up how you like, from tire temps and wear, fuel, lap times, a radar, and more. The dash remembers its layout per game.
  • Tune from the seat: effects on and off with their gains, master and audio capture gain, presets, Telemetry Based FFB and its main knobs, and a car’s name, redline or engine type. Tap any value to type an exact number.
  • FFB Visualizer: scrolling waveforms of the game’s steering force and the haptic layer, as sent to the wheel. Clipping turns the trace red, and a yellow SPIKE badge marks where spike reduction stepped in.
  • An idle card: close the game and the dash becomes your name and number over moving artwork, with the plugin version and any waiting update along the foot. Ten backgrounds, and you set the delay.
  • Make it yours: eight themes, the option to drop to two info boxes if four crowd your screen, and the tabs you don’t use can be hidden or reordered.

TF4ALL Dash

Installs with the plugin and appears in SimHub’s dashboard list.

Community features

Once one driver figures out a car’s redline, fixes its name, or picks its engine layout, everyone driving that same car gets it automatically. Community features are on by default and anonymous: car facts need no account. Turn them off in Settings and the plugin works fully offline (see Privacy).

  • Community preset browser, built into the Presets tab. Browse what other drivers have shared for any game or car, sorted by votes and downloads.
  • Share your own. Game presets, car presets, custom engines, and multi-preset packs can all be shared, with a description attached.
  • Car facts flow back automatically, and converge as more drivers submit agreeing values. Sharing follows your community settings and can be turned off.
  • Downloaded presets stay current. When a curator updates a preset you downloaded, an “updates available” chip surfaces it; apply updates manually or automatically.
  • No account needed; sign-in is optional. It takes an emailed one-time code, no password, and unlocks preset sharing and the Account tab, where you can set a display name, see how your shared presets are doing, export your data, or delete your account.

There is also a Discord server: a place to hang out, swap tunes, ask for help, and get involved. Link your Discord account in the plugin and the achievements you earn grant matching roles there.

Install

  1. Download TrueforceForAll-Setup.exe from the latest release.
  2. Close SimHub if it’s running.
  3. Run the installer. It finds SimHub, copies the plugin files into its install folder, and installs USBPcap if you don’t already have it. No SimHub yet? It points you at the download and waits, so you can install SimHub and press Retry.
  4. Close Logitech G HUB, and keep it closed while you play: running it alongside can cause issues.
  5. Turn on Run as administrator in SimHub’s settings. Reading the wheel’s USB traffic needs it. Without it the force feedback pass-through never starts.
  6. Launch SimHub.

The ? in the panel’s header opens the guides: setup for the games that need it (iRacing, RaceRoom, Le Mans Ultimate, Assetto Corsa, Forza, Farming Simulator), what to do when something is wrong, and the questions people ask most. The guides can also be found here: mhytee.github.io/Trueforce-For-All.

The installer is conservative on uninstall: it removes our files but leaves SimHub, USBPcap, and shared dependencies (HidSharp, NAudio) alone, so other plugins that share those keep working.

Games with native Trueforce

Some titles already ship Trueforce on PC, so the plugin starts on Lightsync only for them: their force feedback and Trueforce are left alone, and only the wheel’s light pattern is set. Switch off the game’s native Trueforce and set the plugin to Normal mode to take over, tuning the feel yourself rather than taking whatever the game hardcodes.

Why a slider at 0 is not off

Many games keep the Trueforce API live even at 0, so the plugin fights a channel the game is still driving and the wheel whines. Only a real on/off switch or a config-file setting fully releases the wheel.

The plugin catches this itself. The USB capture sees every Trueforce packet on the wheel, so when a game streams beside the plugin, the plugin drops to Lightsync only for that game session within a couple of seconds (the log and the status panel say why) instead of whining beside it. Set the plugin to Normal mode to try again once the game’s Trueforce is off. Without USBPcap there is nothing to watch, and nothing changes.

Running MAIRA and the plugin at the same time is not supported: with MAIRA’s RPM lights on, the plugin steps aside for it. Close MAIRA, then set the mode to Normal.

Game How to disable native Trueforce Plugin takes over?
iRacing Set loadTrueForceAPI=0 in app.ini Yes
Dirt Rally 2.0 In-game Trueforce on/off switch Yes
GRID (2019) In-game Trueforce on/off switch Yes
Forza Motorsport (2023) Not tested Yes, through Telemetry Based FFB. Set the mode to Normal first
Automobilista 2 Steam launch option disableTF (try -disableTF if that fails) Likely, untested
Assetto Corsa Competizione Slider only, no off switch found No, stays live
Assetto Corsa EVO Slider only, no off switch found No, stays live
Assetto Corsa Rally Slider only, no off switch found No, stays live
Le Mans Ultimate Settings > Controls > Force Feedback: Vendor Specific Force Feedback off Yes, through the handover: tick “Take over force feedback for Le Mans Ultimate” on the FFB tab

Not tested yet: BeamNG.drive, F1 22 through 25, EA Sports WRC (2023), WRC 10, WRC Generations, Project CARS 3 and Test Drive Unlimited Solar Crown.

AMS2 is a special case: per Reiza’s devs it loads the Logitech SDK but never implements Trueforce, so the channel sits live with nothing on it. The disableTF launch option should let the plugin take over, but I haven’t confirmed it on hardware.

[!NOTE] I don’t own some of these titles, so this table grows from user reports. If you find an off switch or config setting for one of the ones still marked “no”, or get the plugin working on a native-Trueforce game that isn’t listed here at all, please open an issue and let me know.

Known limitations

[!IMPORTANT] Logitech G HUB must stay closed when the plugin is in use. Running it alongside can cause issues.

  • The Trueforce level dial on the wheel doesn’t apply while the plugin is driving Trueforce: the wheel’s own intensity scaling stops responding to it. Use the plugin’s Master Gain and per-effect Gain controls to set intensity instead.
  • Rev lights and the screen depend on who carries the force. They share a control channel with the game’s force feedback, and writing to them while the game’s force passes through the USB capture cuts that force, so the plugin drives them wherever it can (see Per-game enhancements). For the same reason, changing a LIGHTSYNC pattern in a pass-through game interrupts the force for a moment, so it is best done parked. A custom driver that lifts this is in development.
  • The plugin cannot run alongside a game’s own Trueforce. The wheel’s Trueforce stream has room for one sender, so in a native-Trueforce game the plugin stays on Lightsync only unless the game’s Trueforce is switched off (see the table above). Running MAIRA at the same time is not supported for the same reason.

FAQ

Which games does it work with?

The audio-derived effects work in any game at all, since the plugin captures the game’s audio directly with no SimHub support needed. Games that SimHub supports additionally get the telemetry-derived effects (engine pulse, gear shifts, ABS, and so on). Assetto Corsa, iRacing, RaceRoom, Le Mans Ultimate, Forza Motorsport, the Forza Horizon games and Farming Simulator go further with a higher-fidelity direct path (see Per-game enhancements).

Do I need to pay for SimHub?

SimHub itself is free, and the plugin works without a SimHub license. The difference is the telemetry rate: unlicensed, games the plugin doesn’t read directly run at only 10 Hz, which makes the effects feel coarse. A licensed copy lifts that to 60 Hz, which is a big step up in feel. SimHub is cheap and well worth it. (Assetto Corsa, the Forza titles and Farming Simulator are read directly, so their telemetry runs at its own rate whatever the license. The others still take their numbers through SimHub.)

Is this anti-cheat safe?

Yes. For every sim TF4ALL supports, the plugin never injects code into a running game, never reads or modifies game memory, and never hooks the game in any way. It talks to the wheel over USB (via USBPcap), reads telemetry the game publishes (SimHub, shared memory, UDP, or a named pipe), and captures game audio through Windows’ own loopback. Switching off a game’s native Trueforce is done by editing a config file or flipping an in-game setting before launch, never by touching the running game.

Assetto Corsa and Farming Simulator each load a TF4ALL mod, a Custom Shaders Patch script and a mod list entry. The game loads it, so nothing is injected.

Will it change or replace my normal force feedback?

Not unless you ask it to. By default the plugin preserves your existing force feedback and layers haptic effects on top of it; your wheelbase’s own FFB still comes through, with all your usual settings intact. The exception is Telemetry Based FFB, which deliberately builds the steering force from telemetry instead. In the Forza titles that is opt-in and stays off until you turn it on. In Farming Simulator it runs automatically, because the centering spring it replaces is all the game offers. In iRacing, RaceRoom and Le Mans Ultimate, and in Assetto Corsa with the bridge, the force is the sim’s own, carried by the plugin, so it feels exactly as you tuned it.

Why does it need USBPcap, and is that safe?

USBPcap is an open-source USB capture driver. The plugin uses it to read the wheel’s own force-feedback traffic off the USB bus so it can mirror that into the Trueforce stream (this is the FFB pass-through that keeps your normal force feedback alive). It only looks at the wheel’s traffic, it’s widely used and bundled with our installer, and you can uninstall it separately at any time. Games that hand their force over (iRacing, RaceRoom, Le Mans Ultimate, and Assetto Corsa with the bridge) and games running Telemetry Based FFB need no capture at all.

Do I need Logitech G HUB?

No, and it has to stay closed while you play: running it alongside can cause issues.

My normal force feedback disappeared, or the plugin says pass-through is not running.

Run the self-test in the Settings tab’s Diagnostics section. It checks the whole chain and names the part that is missing, USBPcap’s capture driver included. The usual cause is SimHub not running as administrator: reading the wheel’s USB traffic needs it, and without it the pass-through cannot start. Use SimHub’s own Run as administrator setting rather than right-clicking the exe, then restart SimHub.

The effects feel weak or light.

Raise Master Gain and the per-effect Gain in the plugin settings. The Trueforce dial on the wheel itself does nothing while the plugin is running, so all intensity is set in the plugin.

Can I use this in games that already support Trueforce?

By default the plugin starts on Lightsync only for native-Trueforce titles, since the game already provides it, and if both end up streaming at once it steps aside by itself. But you can switch off the game’s native Trueforce and run the plugin instead, which lets you tune the feel yourself. See Games with native Trueforce for which titles allow this and how.

Is it in my language?

TF4ALL ships in several languages; pick yours in Settings. You can translate any language from inside the plugin, and your corrections reach everyone else using it. See Languages and translating.

Supporting the project

The plugin is free and stays that way. It is primarily built by one person, and a Patreon is there for anyone who wants to keep that going. Supporters get cross-device backup and sync of their full setup, and a spot on the supporters wall in the plugin. Manual export and import stay available to everyone.

How it works

The detail

The plugin opens the wheel, runs the Trueforce init sequence, and streams haptics to endpoint 3 at 1 kHz. The effects themselves are synthesized from telemetry or from the game’s own audio, with per-game tuning on top.

A USBPcap-based tap reads the game’s own force feedback off the USB connection. Its plain force is mirrored into bytes 6-9 of that stream, which the wheel takes as its motor torque target, with the rolling window riding on top as an additive overlay. The game’s DirectInput effects, its spring, damper, friction, inertia and waveforms, are decoded from the same traffic and rendered into the stream alongside it.

In some games Telemetry Based FFB is an alternative to capturing. The force is built from the telemetry itself, from per-axle grip and slip and the load through the corner, and some prefer that to what their game sends. For the games that send nothing usable, Farming Simulator among them, it is the only route. Where a sim publishes its own steering torque, that torque is reshaped rather than synthesized.

Some games need no tap at all. Assetto Corsa, iRacing, RaceRoom and Le Mans Ultimate publish their own force values, so the plugin reads them from there and leaves the wheel’s HID++ pipe alone, which is what lets the rev lights and the screen run alongside the force.

The rev lights and the wheel base’s screen take a different path, the wheel’s HID++ control pipe rather than the haptic stream: level and slot writes for the lights, frames for the screen. That pipe carries one writer at a time, so the plugin watches what else is writing to it and stands down while a game is driving the lights itself.

Privacy

Community features are on by default and anonymous; turn them off in Settings and the plugin runs fully offline. What the online features (community presets, car data, sign-in, cloud backup, anonymous usage statistics) store, who processes it, and how to export or delete it is covered in PRIVACY.md.

Acknowledgments

  • mescon/logitech-trueforce-linux-driver: reverse-engineered the wheel’s driver and wire protocol, and later the light-slot protocol (the staging and commit sequence behind the LIGHTSYNC tab). This project would not exist without their work.
  • PeposCJ/LogiDynamicDash: worked out how the wheel base’s OLED screen is driven and documented it publicly. The wheel screen support here is built on that work, and PeposCJ’s captures settled when the wheel’s own pattern selection has to be left alone.
  • Lovely Sim Racing’s car data: the per-car light patterns, per-gear redlines and blink rates behind “Match my wheel to the car”, shared under CC BY-NC-SA 4.0.
  • Andrew Boersma: built the telemetry-based force feedback engine and the axle slip, curb thump, and lockup judder effects. The headline features of the 0.2.0 release are his work.
  • USBPcap by Tomasz Mon: the kernel-mode USB filter that lets us tap the wheel’s bus traffic for FFB pass-through.
  • mdjarv/assettocorsasharedmemory: community reference for AC’s shared-memory layout, used to validate our SPageFilePhysics field offsets.
  • HidSharp: cross-platform HID library used for the control-side of wheel communication.
  • NAudio: audio I/O library used for the per-process loopback capture pipeline.
  • ManteoMax’s Forza Horizon 5 spreadsheet: the canonical community catalog mapping Forza CarOrdinal to year/make/model and engine specs. Our FH5 lookup (engine cylinder / layout / electric detection plus auto-named per-car presets) is built from this data.
  • SimHub: the host application. This plugin is unofficial and not affiliated with the SimHub project.
  • Armando Ramirez: produced a video walkthrough of the plugin in Forza Horizon 6 and tuned his own presets for it.
  • Revasio: produced a French-language installation tutorial on TikTok, helping French-speaking drivers get set up.
  • Svenmoor: tested the plugin against a range of native-Trueforce titles and mapped which ones have a true Trueforce off switch (so the plugin can take over cleanly) versus which only expose an intensity slider, which populated the “Games with native Trueforce” table above.
