This is a modern engine created for OpenSandbox.
From Quake3e:
- 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
- \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
SourceTech features:
- Brush limit up to 524288
- Entity limit up to 4096-16384 (4096 by default)
- Model limit up to 4096
- Sound limit up to 4096
- Brush model limit up to 4096
- Cvar limit up to 16384
- Players and bots limit up to 64-512 (99 by default)
- New weapon system with limit up to 65535
- Up to 80000000 polygons per scene
- Up to 1000000 polygons per model
- New addon system
- Simple physics (QVM-side)
- Map in UI background (for single player games)
- Per map QVMs
- Improved lighting (high resolution lightmaps and post-processing)
- Render distance for entity (server-side)
- NSGui interface system with QVM and map integration
- Vehicles and additional properties of the entity
- Support huge size maps up to 4GB
- PostFX (bunch a ARB shaders)
- BSP collision files for visible models
- Anticheat engine (anti wallhack)
Based on Quake-III-Arena-Kenny-Edition/quake3e with many additions:
- 4K textures support
- High-quality per-pixel dynamic lighting
- Merged lightmaps (atlases)
- Smooth shader animations with 64 frames
- Rendering a huge number of entities
Highly recommended to use on modern systems
Based on classic OpenGL renderers from idq3/ioquake3/cnq3/openarena/quake3e, features:
- 4K textures support
- High-quality per-pixel dynamic lighting
- Merged lightmaps (atlases)
- Smooth shader animations with 64 frames
- Rendering a huge number of entities
Performance is usually greater or equal to other opengl1 renderers
