It should eventually be possible to run the engine efficiently in many different hardware environments, including the following:
| Standard | Features | Hardware Class |
|---|---|---|
| Mesa 3D | Software rendering | pre-T&L |
| OpenGL 1.x | Fixed T&L | "DX7" desktop |
| OpenGL 2.x | Vertex/Fragment Shaders | "DX9" desktop |
| OpenGL 3.x | 2.x + Geometry Shaders | "DX10" desktop |
| OpenGL 4.x | 3.x + Tesselation/Compute Shaders | "DX11" desktop |
| OpenGL ES 1.x | Fixed T&L | OpenGL 1.5-class embedded |
| OpenGL ES 2.x | Vertex/Fragment Shaders | OpenGL 2.0-class embedded |
| WebGL | Vertex/Fragment Shaders | OpenGL ES 2.x-class |
