Latest version of display drivers found
According the database, you are running the latest display drivers for your video card.
Compiled vertex array support
This feature improves OpenGL performance by using video memory to cache transformed vertices.
Multitexture support
This feature accelerates complex rendering such as lightmaps or environment mapping.
Secondary color support
This feature provides an alternate method of coloring specular highlights on polygons.
S3TC compression support
This feature improves texture mapping performance in some applications by using lossy compression.
Vertex array range support
This feature improves performance in some applications by using AGP for dynamic vertex transformation.
Texture edge clamp support
This feature improves texturing quality by adding clamping control to edge texel filtering.
