Well I decided to do a few benchmarks of my own to compare the last 3 drivers released. Be aware that in my benchmarks I am running everything in highest quality but NO AA. All tests were done with PhysX 8.08.01 and are based on an average of 4 runs. My test rig: Windows Vista X64 q6600 @ 3500.00 Evga 9800 GTX+ 2x2 pc8500 OCZ Reaper 5-5-5-15 @ 1089 XFX 780i MB 177.79 3Dmark06 14,682 Nurien Avg FPS 53.54 FluidMark Avg FPS 85 @ 1920/1200 Metal Knight Zero Avg FPS 61 @ 1920/1200 3DMark Vantage P8675 177.83 3DMark06 14,679 Nurien Avg FPS 53.94 FluidMark Avg FPS 85 @ 1920/1200 Metal Knight Zero Avg FPS 60 @ 1920/1200 3DMark Vantage P8681.5 177.89 3DMark06 14,684.5 Nurien Avg FPS 54.74 FluidMark Avg FPS 87 @ 1920/1200 Metal Knight Zero Avg FPS 59 @ 19200/1200 3DMark Vantage P8196 Vantage score is way low on 177.89 compared to previous drivers?? I think the 177.79 have the best REAL WORLD results for my system; however, the 177.83 seem to give almost identical results and are ROCK STABLE. ENJOY!
