I'm truly shocked with these drivers. I can't believe the performance boost i got and i double checked them. Here are some benchies in Windows XP 32Bit:
Intel Core Duo 2 Core 6600 (3.51Ghz), GTX295 (710/1180) , ForceWare 186.08
Doom3: 1600x1200 + 8xFSAA + 16xAF + Ultra Quality= 182.7
Aquamark=185964
3D Mark 2006= 16927
Codecreatures 1920x1440 + 4xFSAA + 16xAF = 175.2
Crysis: 1600x1200 + Tweaked Very High + 16xQSAA + 16xAF= 40.98
The Last Remnant: 2048x1536 + 16xAF: 111.10
DMC4: 1600x1200 + Max settings + 16xCQAA + 16xAF = 219.38 / 158.99 / 273.11 / 140.33
SF4: 2048x1536 + Max Settings + 16xCQAA = 7332
Intel Core Duo 2 Core 6600 (3.51Ghz), GTX295 (710/1180) , ForceWare 190.15
Doom3: 1600x1200 + 8xFSAA + 16xAF + Ultra Quality= 191.7
3D Mark 2005:1024x768= -
Aquamark=190865
3D Mark 2006= 17053
3D Mark 2003= -
Codecreatures 1920x1440 + 4xFSAA + 16xAF = 155.2
Crysis: 1600x1200 + Tweaked Very High + 16xQSAA + 16xAF= 45.77
The Last Remnant: 2048x1536 + 16xAF: 129.66
DMC4: 1600x1200 + Max settings + 16xCQAA + 16xAF = 220.68 / 170.34 / 276.76 / 147.88
SF4: 2048x1536 + Max Settings + 16xCQAA = 7430
Almost 10fps increase in Doom3, 5fps in Crysis,18fps in The Last Remnant (and the stuttering that was present in specific places is gone) and a little increase in both DMC4 and SF4. Only Codecreatures was slower but it is a synthetic bench so who gives a sh!t.
To nail it, i tested Prototype. With the 186.08, there were a few places in the first mission that i was getting pretty low fps (around 20 and i'm not kidding. 1600x1200 + 4xFSAA + 16xAF + Max Settings). Right now with the 190.15, the lowest i've seen is 30. Prototype runs better, that's for sure. And basically every game i tested. I HIGHLY recommend them.
