Anyone else seeing this with 6800GT(61.77/dx9.0c)?
Notice the 1280 with 4x aa scores and compare.

D3 timedemo demo1 -

1280x1024 High Quality no AA (in D3 options, not NV CP)
66.8 FPS

1280x1024 High Quality 4xAA (in D3 options, not NV CP)
84.0 FPS

1600x1200 High Quality no AA (in D3 options, not NV CP)
67.2 FPS

1600x1200 High Quality 4xAA (in D3 options, not NV CP)
59.3 FPS

I've rebooted, shutdown & restarted - it's always consistent. The 1280x1024 with 4xaa enabled is smoking all my other numbers. The only change I made was the cache size from 20 to 512 but I've run all tests the same way and use the score on the second run. I'm running a 3400+ @ 212 FSB - 2330 Mhz overall clock speed. 1GB XMS3200XL @ 2-2-2-5 DDR424. The funny thing is that the 1600x1200 and 1280x1024 scores are the same which leads me to believe I'm CPU limited with this rig - at 1600x1200???? The GT is at STOCK speeds btw.

Oh, and Get this -

Sapphire X800 Pro
1280x1024 High Quality no AA (in D3 options, not NV CP)
51.3 FPS

1280x1024 High Quality 4xAA (in D3 options, not NV CP)
30.6 FPS
