fps with 6850 crossfire
« on: March 05, 2011, 11:07:05 pm »
Hey everyone, I have a crossfire setup on a gpa-890-3udh. No matter what games i play I never get above 60fps. I mean this is cool, all games rock, no stutter or lag but I am wondering if this is a function of the drivers leveling off output or what?

I can't see any reason for your graphics to be limited but AMD isn't my side of things so I expect absic or one of the other AMD guys will be more help to you here. It is possible that the throughput is being limited but  am unsure how the particular system works.

I think this is caused either by Vsync or some in-game FPS block. Some games have internal limit of 60 FPS and there's nothing you can do about that. If anything, you could probably overclock the CPU some more as Crossfire / SLI like as much CPU power as they can get.

In the end, limiting FPS to 60 is good in that you shouldn't be able to tell much of a difference with FPS any higher and this way you're using only as much computing power as needed.
