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.
This repository do not contains any game content so in order to play you must copy 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
- 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
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- multi-sample anti-aliasing (\r_ext_multisample)
- 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
- 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
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:
- high-quality bloom/reflection post-processing effects
- supersample anti-aliasing (\r_ext_supersample)
Performance is usually greater or equal to other opengl1 renderers
Original ioquake3 renderer, performance is very poor on non-nvidia systems, unmaintained
Install Visual Studio Community Edition 2017 or later and compile quake3e
project from solution
code/win32/msvc2017/quake3e.sln
Copy resulting exe from code/win32/msvc2017/output
directory
To compile with Vulkan backend - clean solution, right click on quake3e
project, find Project Dependencies
and select renderervk
instead of renderer
All build dependencies (libraries, headers) are bundled-in
Build with either make ARCH=x86
or make ARCH=x86_64
commands depending from your target system, then copy resulting binaries from created build
directory or use command:
make install DESTDIR=<path_to_game_files>
You may need to run following commands to install packages (using fresh ubuntu-18.04 installation as example):
- sudo apt install make gcc libcurl4-openssl-dev mesa-common-dev
- sudo apt install libxxf86dga-dev libxrandr-dev libxxf86vm-dev libasound-dev
- sudo apt install libsdl2-dev
Build with: make
Copy resulting binaries from created build
directory or use command:
make install DESTDIR=<path_to_game_files>
Several make options available for linux/mingw builds:
BUILD_CLIENT=1
- build unified client/server executable, enabled by default
BUILD_SERVER=1
- build dedicated server executable, enabled by default
USE_SDL=0
- use SDL2 backend for video, audio, input subsystems, disabled by default
USE_VULKAN=0
- link client with vulkan renderer instead of OpenGL, disabled by default
USE_RENDERER_DLOPEN=0
- do not link single renderer into client binary, compile all renderers as dynamic libraries and allow to switch them on the fly via \cl_renderer
cvar, disabled by default - not recommented due to not stable renderer API
USE_SYSTEM_JPEG=0
- use current system JPEG library, disabled by default
Example:
make BUILD_SERVER=0 USE_VULKAN=1
- which means do not build dedicated binary, build client with static vulkan renderer
