Thanks for the Demo Humus! I just gave it a try on my HD2900 Pro/1G (800/1.000) in Vista x64 w/ Cat8.3
1.600x1.200 (as that seems to be some common ground)
Results in Fps, w & w/o custom resolve
No AA: 533/533 (obviously)
2x AA: 330/299
4x AA: 211/347
8x AA: 101/300
Now, that's strange.
One more go in 2.560x1.600
No AA: 265/265
2x AA: 161/146
4x AA: 99/181
8x AA: 47/155
Same relations here. Bandwidth (at least from VRAM) should not be an issue at a rate of 128G/sek.
edit:
Even more strangely: If i 'fly' out of the castle so that only some background tex is in view, i am hitting a wall at 50 Fps w custom resolve. If i switch off CR, Fps jump to 250ish. What exactly is the demo doing with CR? No Edge-checking whatever, just every Pixel gets custom resolved?
