real-time calculated shadows can be switched to use detailed lightmaps instead of real-time per-pixel lighting what makes the engine run on slower computers very fast portal based engine enhanced materials and material effects reflecting, refracting and transparent materials mirrors real-time calculated specular highlights support for T&L support for almost all advanced features of today's 3D accelerators like: Pixel Shaders
Vertex Shaders
Cube Mapping
Bump Mapping
renders bezier curves and patches with real-time calculated level of details in-house made editor which considerably speeds up level editing volumetric fog mesh deformation using displacement maps detailed characters with muscles and facial expressions advanced particle system special effects for cut-scenes (e.g. black and white scenes, blur, sharpen, fading of scenes, etc.) cloth simulation
