Appendix C NVIDIA ForceWare Graphics Display Driver - Feature History 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 and Quadro, 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 multitextured TexCoord2f+Color4ub+Vertex3f • vertex array range extension is fully functional • Control Panel enables accelerated full-scene anti-aliasing (GeForce, Quadro, GeForce2) • multi-monitor hardware is accelerated on Windows 2000 • GL_WGL_swap_interval extension can change V-sync behavior • V-sync is on by default (default behavior is selectable with the Control Panel) • default anisotropic filtering can be triggered by checking the anisotropic filtering box on the Control Panel • enabling GL_POLYGON_SMOOTH no longer forces software rendering, resulting in much better performance at some cost in visual quality Direct3D Release 5 contains the following Direct3D changes: • accelerated full-scene anti-aliasing is enabled (GeForce, Quadro, GeForce2) • limited three-stage setup is now possible • D3DVTXPCAPS_MATERIALSOURCE7 capability bit is now disabled (leaving the driver with DirectX 6 material source capabilities) The following Registry keys are useful for applications that do not blit correctly: • FLUSHAFTERBLITENABLE is a new Registry key that controls the wait-after-blit condition when the DDBLT_WAIT flag is set. (Default is DISABLED-do not wait.) Note: This Registry key was formerly named WAITAFTERBLITENABLE. NVIDIA Corporation 207
