Crysis scales for me, running 2 x 4850, 8.6 Hotfix, Vista x64 Ultimate, running 32bit exe (don't ask), 1.21 patch.
I'm on P35 atm (X38 on its way), so the 2nd card is bottlenecked, but I still get performance boost from enabling the 2nd card in Crysis.
1280 x 1024, ALL HIGH, NO AA :
Single Card = 44.55 FPS
Crossfire = 50.35 FPS
1280 x 1024, ALL HIGH, 4x AA :
Single Card = 34.9 FPS
Crossfire = 41.06 FPS
1680 x 1050, ALL HIGH, NO AA :
Single Card = 35.03 FPS
Crossfire = 41.35 FPS
1680 x 1050, ALL HIGH, 4x AA :
Doesn't Scale - Same result from 1 or 2 cards, possibly limited due to 4x PCI-E slot.
