ETXreaL is a graphics mod for Wolfenstein: Enemy Territory using the enhanced XreaL id Tech 3 GPL engine.

• Modern OpenGL 3.2 renderer with all deprecated OpenGL calls removed
• Clever usage of vertex buffer objects (VBO) to speed up rendering of everything
• Avoids geometry processing each frame using the CPU (worst bottleneck with the Q3A engine)
• Renders up to 500 000 - 1 000 000 polygons at 80 - 200 fps on current hardware (DX10 generation)
• Optional GPU occlusion culling (improved Coherent Hierarchy Culling) useful for rendering large city scenes
• Doom 3 .MD5mesh/.MD5anim skeletal model and animation support
• Unreal Actor X .PSK/.PSA skeletal model and animation support
• True 64 bit HDR lighting with adaptive tone mapping
• Advanced projective and omni-directional soft shadow mapping methods like EVSM
• Real-time sun lights with parallel-split shadow maps
• Optional deferred shading
• Relief mapping that can be enabled by materials
• Optional uniform lighting and shadowing model like in Doom 3 including globe mapping
• Supports almost all Quake 3, Enemy Territory and Doom 3 material shader keywords
• TGA, PNG, JPG and DDS format support for textures
• Usage of frame buffer objects (FBO) to perform offscreen rendering effects
• Improved TrueType font support that does not require external tools
• Linux 64-bit support
• Linux sound backend using SDL
• .avi recorder from ioquake3 including sound support
• Optimized collision detection routines
• Support for Omni-bot
