*Posted in wrong section (I'm so pro), could a mod move this to graphics cards please? Cheers*

Hey all,

I'm having some VERY frustrating problems with my Crossfire setup and was wondering if you could help me solve them.

First of, Resident Evil 5, running the bench with Crossfire enabled or disabled in CCC seems to make hardly any difference to FPS what so ever, I've also noticed that I'm not getting over 60FPS 100% of the time in Crysis on all very high with no AA which I find ridiculous (at 1920x1200). I've checked usage/clocks and both go up when the game is playing but it doesn't actually seem to increase the performance!

Another thing: CCC and MSI Afterburner really don't seem to like each other, I'm using MSI to overclock to 900/1375 but sometimes it just defaults back to 800/1250 and no amount of fiddling with MSI gets the clocks back up?! Similarly with fan control in CCC and my MSI fan profile; CCC always reverts back to 'control fan speed manually' yet I never tick it and sometimes the fans just jump to 50% when CCC loads despite MSI's fan profile still running.

Power control settings don't seem to stay for very long, I set it to 20% but every now and again I'll go in to CCC to find that it's been reset back to 0.

Lastly, in another thread recently I asked about switching which is the main GPU but I'm not sure whether or not my motherboard can do it? There's an option to change the initial display port but this does not seem to switch around the GPU number assignment. All that the option has done is to disable any output display until windows loads and if I plug the monitors in the other card I only get a display up until when windows loads :mad:

Just about had it if I'm honest, my setup just does not seem to want to work and that extra 200 quid feels like a total waste of money.

Turn off V-sync to get over 60fps.

But it's better to leave it on as your monitor can physically only refresh the image 60 times per second.

I don't have vsync on I'm when I'm looking at fps differences, that would be stupid.

Actually, don't know if its related but vsync refuses to work on CSS.
