Detonator 3 Vs. Detonator 2 - SPECviewperf 6.1.2
The next set of results will probably bore you quite badly. Although NVIDIA claimed major improvement of OpenGL-performance with Detonator 3, you can hardly find any of it looking at the Viewperf scores.
If anything, Detonator 3 is slower than Detonator 2 with several cards under Linux.
The Windows 2000 performance of Detonator 3 doesn't seem to be worth changing to this driver as well.
