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.
Key features:
- optimized OpenGL renderer
- optimized Vulkan renderer
- raw mouse input support, enabled automatically instead of DirectInput(\in_mouse 1) if available
- unlagged mouse events processing, can be reverted by setting \in_lagged 1
- \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
- raized 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 bugfixes 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 reguires 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 original KE's version
Highly recommended to use on modern systems
OpenGL renderer
Based on classic OpenGL renderers from id/ioq3/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
