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
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
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
