# Quake3e [![build](../../workflows/build/badge.svg)](../../actions?query=workflow%3Abuild) * Discord server 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](https://github.com/ioquake/ioq3) with latest upstream fixes applied. Go to [Releases](../../releases) section to download latest binaries for your platform or follow [Build Instructions](#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](https://github.com/kennyalive/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](https://developer.nvidia.com/content/depth-precision-visualized) 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](https://renderdoc.org/) * 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](https://github.com/id-Software/Quake-III-Arena)/[ioquake3](https://github.com/ioquake/ioq3)/[cnq3](https://bitbucket.org/CPMADevs/cnq3)/[openarena](https://github.com/OpenArena/engine), 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 ## [Build Instructions](BUILD.md) ## Contacts Discord channel: https://discordapp.com/invite/X3Exs4C ## Links * https://bitbucket.org/CPMADevs/cnq3 * https://github.com/ioquake/ioq3 * https://github.com/kennyalive/Quake-III-Arena-Kenny-Edition * https://github.com/OpenArena/engine
