I know you guys don't like Beta drivers but I thought these were worth a mention. nVidia has leaked the 66.00 series out onto the net. I just benched them in 3dMark01 and I'm up 221 points. This is quite impressive seeing the last sets released were only giving me gains of about 10 or 20 points.
I'm up from a sad 4061 points to 4282 points. I haven't run 3dMark03 yet. I'll let the computer cool off a bit and then I'll try it later.
I ran the test at 1024x768x32 resolution with 8x AF and no AA. I set the bench program use Pure Hardware T&L. I'm using DirectX 9.0c.
As for preformance in FS2004, it does seem smoother. No word on frame boosts. I'll test those later as well.
