[CF] Guild Wars FPS drop

[Iska]

Hey everyone,

I just installed Vista x64 Ultimate because I was unable to start CF in Win XP. Fortunately, Vista was more comprehensive and I was enabled to enable/disable Crossfire (2x MSI ATI Radeon 4850), but...
When I play Guild Wars without Crossfire at max. settings I've got about 250 fps and GPU #1 is running at about 90% GPU load. So you might expect about 400 fps with Crossfire enabled, but instead of that I've got about 160 fps because my GPU load at GPU #1 dropped to about 25% and the GPU load of GPU #2 to about 40%! Same thing happens with 3DMark and Crysis :S

Does anyone have a solution for this? It's now 3 months since I got this system and it's still not working :S:S

Thanks in advance,
Iska

System specs: Intel C2D E8400@3,5ghz, Foxconn Mars, 4gb 1000mhz, 2x MSI 4850's CF, 2x 19"W, Win Vista Ult. x64, RAID 0 (2x 160 gb)..

Guild Wars stays pegged at my monitor's refresh rate on my EAH3850; I've not wasted my time to see how much higher it would actually be. I'd say drop the Crossfire, as it is entirely unnecessary with Guild Wars.
