I've recently installed another HD 5850 into my rig, hoping to improve the performance in Crysis Warhead, but I saw no performance increase at all. I created a benchmark that ran 60FPS with a single card, and that benchmark now runs 53FPS with 2 cards in CrossFire.
I know Crysis isn't a game that scales very well at all, but I thought Crysis Warhead was much improved in SLI and CrossFire performance.
Is there something not right? My 3DMark Vantage scores went from 16500 to 22300 on performance settings, so I know both cards are working.
However, I run the game at 1280x1024 resolution because I have an older monitor, but that still does not explain why I would get LESS FPS with CrossFire.
The second PCI Express slot on my mobo is x4 operation, so I OC'd the card in that slot to 850/1100(725/1000 stock), and the primary card is at 840/1060.
I also tested this in GTA 4, and omfg it's very choppy, not in terms of FPS but it seems like it has to have a 3FPS loading moment everywhere I look before it goes up to 50FPS or so.
Does anyone know if theres something wrong with my setup? or maybe this is how its supposed to be?
