Quake3e
* 
This is a modern Quake III Arena engine aimed to be fast, secure and compatible with all existing Q3A mods.
It is based on last non-SDL source dump of ioquake3 with latest upstream fixes applied.
Go to Releases section to download latest binaries for your platform or follow Build Instructions
This repository does not contain any game content so in order to play you must copy the resulting binaries into your existing Quake III Arena installation
Key features:
- optimized OpenGL renderer
- optimized Vulkan renderer
- raw mouse input support, enabled automatically instead of DirectInput(\in_mouse 1) if available
- \in_minimize - hotkey for minimize/restore main window (win32-only, direct replacement for Q3Minimizer)
- \video-pipe - to use external ffmpeg binary as an encoder for better quality and smaller output files
- significally reworked QVM (Quake Virtual Machine)
- improved server-side DoS protection, much reduced memory usage
- raised filesystem limits (up to 20,000 maps can be handled in a single directory)
- reworked Zone memory allocator, no more out-of-memory errors
- non-intrusive support for SDL2 backend (video, audio, input), selectable at compile time
- tons of bug fixes and other improvements
Vulkan renderer
Based on Quake-III-Arena-Kenny-Edition with many additions:
- high-quality per-pixel dynamic lighting
- very fast flares (\r_flares 1)
- anisotropic filtering (\r_ext_texture_filter_anisotropic)
- greatly reduced API overhead (call/dispatch ratio)
- flexible vertex buffer memory management to allow loading huge maps
- multiple command buffers to reduce processing bottlenecks
- reversed depth buffer to eliminate z-fighting on big maps
- merged lightmaps (atlases)
- multitexturing optimizations
- static world surfaces cached in VBO (\r_vbo 1)
- useful debug markers for tools like RenderDoc
- fixed framebuffer corruption on some Intel iGPUs
- offscreen rendering, enabled with \r_fbo 1, all following requires it enabled:
screenMap texture rendering - to create realistic environment reflections- multisample anti-aliasing (\r_ext_multisample)
- supersample anti-aliasing (\r_ext_supersample)
- per-window gamma-correction which is important for screen-capture tools like OBS
- you can minimize game window any time during \video|\video-pipe recording
- high dynamic range render targets (\r_hdr 1) to avoid color banding
- bloom post-processing effect
- arbitrary resolution rendering
- greyscale mode
In general, not counting offscreen rendering features you might expect from 10% to 200%+ FPS increase comparing to KE’s original version
Highly recommended to use on modern systems
OpenGL renderer
Based on classic OpenGL renderers from idq3/ioquake3/cnq3/openarena, features:
- OpenGL 1.1 compatible, uses features from newer versions whenever available
- high-quality per-pixel dynamic lighting, can be triggered by \r_dlightMode cvar
- merged lightmaps (atlases)
- static world surfaces cached in VBO (\r_vbo 1)
- all set of offscreen rendering features mentioned in Vulkan renderer, plus:
- bloom reflection post-processing effect
Performance is usually greater or equal to other opengl1 renderers
OpenGL2 renderer
Original ioquake3 renderer, performance is very poor on non-nvidia systems, unmaintained
