GTX 570 SLI utilization

I am having some issues with my sli utilization while in games, particularly the witcher 2. My utilization for both GPU's never exceeds 45% with msi afterburner, while my cpu usage is being displayed as 100% in task manager.

Currently, I have my cpu set to 4.4ghz with the preset option offered by my mobo, so I don't it's a bottleneck. Also, all video drivers have the latest update. Anyone got any ideas? You would think you would see a better frame rate with 2 cards over 1. .

  1. Can you tell your full system spec? 4.4Ghz doesn't say much when we have no clue on the brand or number of cores :P
  2. Sorry, forgot to paste it. lol

    Cpu - I5 2500k OC 4.4ghz
    Cooler - Hyper 212 plus
    Mobo - ASrock p67 Extreme4
    GPU - EVGA 2x GTX 570 SLI
    Ram - 2 4gb Corsair Vengeange 1600
    HDD - WD velociraptor 600gb
    PSU - Corsair HX 850watt
    - Creative Sound blaster X-fi titanium
  3. Does witcher 2 use the CPU vs the GPU, in other words it uses the CPU more then the GPU.
  4. yes, it seems the cpu stays at a steady 100% while playing, where the gpu's stay around a 45-50%. Only getting like a 30-35 FPS, which is about the same as just using one card.
  5. Update you nVidia drivers to the latest, and check Whitcher 2 benchmarks in SLI but i guess it's high than what you're saying, it's like the game is not benefiting from SLI or you probably have some failure with your SLI.

    What's your gaming resolution ? and how many FPS you get in Crysis 2, Metro 2033, any DX11 game ?

    All of my drivers have been updated to their most recent versions. My resolution is set at 1920 x 1080. I do not own any of those games mentioned above. This is my first SLI configuration, and now I'm starting to see why some say one big card FTW. :??:
