• level-of-detail control for mipmapped textures (supported in software on
TNT2)
• texture coordinate edge clamping
• 3D textures (performed in software on all platforms)
• vertex array subranges for optimizing vertex array processing
(
glDrawRangeElements()
retains the performance of
glDrawElements()
)
OpenGL Extensions
were added or changed in Release 5.
OpenGL Performance Enhancements
A number of features are significantly improved in Release 5.
• For RIVA TNT and TNT2, polygon offset is faster.
• For GeForce 256, a number of improvements have been made:
•
glDrawPixels()
and
glReadPixels()
have been made faster
•
Display lists use AGP memory for better performance.
•
Large texture sets are handled more efficiently by the texture manager.
•
Vertex arrays with two-sided lighting are faster.
•
Compiled vertex arrays are faster for primitives that use multi-textured
TexCVertex3f.
•
Vertex array range extension is fully functional.
• Windows
