My custom built desktop runs super fast, except when it comes to gaming. For some reason, my graphics card doesn't run games very well. I have a Sapphire 6870, actually 2 (crossfire) and when I play games like battlefield 3 I only get about 27-45 frames per second on ultra graphics, and with Skyrim I only get around 27-39 frames per second on ultra. I read online that my specs should be more than enough to handle it. Running only one card, it runs well but doesn't get as high of a performance as crossfire. Few things you should know first though:
-FPS dips randomly, lags occasionally on simple games like Black ops (stays at 60 FPS then drops all of a sudden to 40 while lagging for about 5 seconds, then shoots back up to 60)
-When playing skyrim, even when it is installed on my solid state, it lags when I do a quick turn (look around fast)
-Both are the same exact cards and model number, cross fire is shown to be enabled in both CCC and GPU-Z
-When monitoring my GPU usage on my second graphics card in GPU-Z, it shows that there is 0% activity where my primary video card has about 7% idle, and my secondary stays 0% even after intense gaming
-Both graphics cards are plugged in 16X PCI-Express ports but only one of them is using 16X while the other is using 4X (no idea why, bios only gives me the option to enable 4X)
I'm not sure where I went wrong with my crossfire, I have already uninstalled and reinstalled the drivers multiple times, done a driver sweeper and both CCC and GPU-Z show they are working properly, except for the fact in GPU-Z it shows 0% activity. Any troubleshooting tips or experiences with fixes would be extremely helpful.
