Guest RET.CW2.POLLVX=US= Posted October 20, 2011 Share Posted October 20, 2011 I just received my new 6950 and installed it with Crossfire. CCC and GPU-Z both inform me that Crossfire is enable. My first card is in an x16 slot and the second is in an x8 slot. I'm running one bridge (as that's all I have). Now the problem: my games are running with lower frame rates. BFBC2 in 5906x1080 runs at 45fps (no change) and Unigine Heaven runs at 8fps (ran at 13.5fps with a single card). I've installed the latest CAP from AMD and I have 11.9 installed for the driver. Any ideas?

Guest MarkyGman Posted October 20, 2011 Share Posted October 20, 2011 Sgt, Generally in a PCIe 2.0 setup , there is VERY little loss in a 16x to an 8x. Since you have dual 8x slots. Try running both cards in both 8x slots in Crossfire, and see if that brings your FPS up. Link to comment Share on other sites More sharing options...
Guest RET.CDR.CrAzY_NuTtA=US= Posted October 20, 2011 Share Posted October 20, 2011 Whether it's any help or not, in my old rig of 4850s i experienced exactly the same fps when using crossfire as i did without. However, i never experienced a drop. It may be that BC2 is just badly coded to run crossfire?? Sorry i can only suggest google is your friend.

Guest RET.CW2.POLLVX=US= Posted October 21, 2011 Share Posted October 21, 2011 I enabled the AMD Crossfire watermark and it appears in BFBC2. When I checked the load, the first card ran at 97%-99% and the second card at 57%. My processor never jumped above 60%. This is really frustrating. Playing across three monitors is more trouble than it's worth. All I want is my three monitors running BF3 at 45+ fps. There has to be something wrong with my setup.

Guest RET.CW2.POLLVX=US= Posted October 21, 2011 Share Posted October 21, 2011 To anyone who cares: the problem does not lie with Crossfire, but Eyefinity. When I run BFBC2 maxed out on every setting with 1920x1080 my average FPS is 115-125. From what I've read online (thanks for the tip Commander :P ) the two do not work well together, which makes no sense. Why have the ability to put a lot of pixels on three screens when technology that would let that run smooth doesn't work? Thanks AMD! Link to comment Share on other sites More sharing options...
Guest Navi491 Posted October 21, 2011 Share Posted October 21, 2011 Nvidia for the win? :P Glad to see your problems were solved Sgt. Pollvx Link to comment Share on other sites More sharing options...
Guest RET.CW2.POLLVX=US= Posted October 21, 2011 Share Posted October 21, 2011 Glad to see your problems were solved Sgt. Pollvx My problem is not resolved. Playing across three monitors has decreased performance with Crossfire. When I play single screen it works great. Link to comment Share on other sites More sharing options...
