wake boy45 Posted February 9, 2014 Posted February 9, 2014 So I have an i7 2600k, 7970 cf w/ 280x, 14gig ddr3, ssd, 750w psu and all that and I am getting about 35-36 fps average on Heaven with dx11, ultra quality, extreme tessellation, AA x8, 1920x1080. People are saying they're getting 70+ fps from cf 280x's. The 7970 is the same as the 280x so why am I under performing this badly?

wake boy45 Posted February 9, 2014 Posted February 9, 2014 Yeah MSI afterburner shows second GPU usage. Share this post Link to post Share on other sites More sharing options...
wake boy45 Posted February 9, 2014 Posted February 9, 2014 I've also noticed my GPUs have been running a lot cooler lately. Don't know if that is a symptom of something... Share this post Link to post Share on other sites More sharing options...
Waco Posted February 9, 2014 Posted February 9, 2014 Does Afterburner show them both maxed out when running Heaven? They should be at 99%-100% running Heaven. Share this post Link to post Share on other sites More sharing options...
wake boy45 Posted February 9, 2014 Posted February 9, 2014 For heaven it shows no activity from my second GPU..... I will get like 125-150 fps on BF4 Operation locker for about 10 minutes and then I will start getting about 70 fps and drops to 40.

wake boy45 Posted February 10, 2014 Posted February 10, 2014 On BF4 it shows that its not staying at 100 percent usage. Share this post Link to post Share on other sites More sharing options...
Waco Posted February 10, 2014 Posted February 10, 2014 That means it's not using your second GPU in Heaven - you just found your problem. Share this post Link to post Share on other sites More sharing options...
wake boy45 Posted February 10, 2014 Posted February 10, 2014 Indeed I have found the problem, do you know what I could do to fix this problem? Share this post Link to post Share on other sites More sharing options...
wevsspot Posted February 10, 2014 Posted February 10, 2014 Single monitor or multiple monitors? Regardless, in the Heaven options menu make sure that "multi-monitor" option is disabled. Also make sure to run the benchmark in fullscreen mode. Are you running Heaven 3.0 or Heaven 4.0? Share this post Link to post Share on other sites More sharing options...
wake boy45 Posted February 10, 2014 Posted February 10, 2014 Heaven 4.0 and single monitor and multi-monitor is disabled. What's the reason my cards are not running 100% in BF if I'm not getting constant 60 frames? I'll be getting crazy frame rates but it's literally like the card just starts to fuck around and get lazy and just doesn't do 100% usage.

WarWeeny Posted February 10, 2014 Posted February 10, 2014 The only thing i can think of is the psu not delivering enough power to the card. How old is the PSU you have? A second though could be driver issues, be sure to have it on 3D performance when you run Heaven or any heavy graphical applications.
