Why does my FPS drop suddenly until I alt-tab out?

    Hi,

    when I play games like diablo 3, there are random times when my FPS just reduces in half. It clears up until I alt tab out, and return to the game. Anyone know why this happens?

    Specs are GTX 670 and i5-3570K @ 4300MHZ

    Thanks

    card may be throttling or going into power saving mode. Run GPU-z to log the information from the sensors next time you play and see if there is anything odd there. Look for spikes in temperature or some other anomaly at the time the card looses FPS.

    Could it be a driver bug? What versions of nVidia's driver are both of you running because I find it interesting that both of you have the same problem and the common link between your two rigs are a GeForce 600-series cards.

    I do have the most recent driver (from last week).

    Also, my temperature is fine, it never goes above 64C under load.

    Also, drop in FPS happens at such a random sequence; especially when I'm moving to a new area

    What are some of the ways to reduce the GPU heat? I mean, I'm not even overclocking....

    But I can try and remove some cables out of the way, as I remember my cables are literally all over the place and it's a huge mess. I need a better air flow inside the case.

    Enable Triple Buffering, Adaptive VSync and Frame Limiter.

    Thanks for your reply.

    I'm a noob here, can you explain what you mean by "Memory Leak"?

    When you can fix an FPS drop with an Alt-Tab that normally means you have a Memory leak. Skyrim and Fallout are known for this.

    A probable driver update will fix it or a game patch/update for the particular game in your case diablo 3 or any other game with the issue

    Driver is up to date as mentioned before, and it's happening to other games too, not all, but select games.

    I meant a future driver update BETA or WHQL, this applies for future game patches/updates, and NOTE I'm saying its all just a probability

    Did you try rolling back to an older driver?

    physically, get a fan blowing air into the gpu. like one on the side panel. or cleanning the gpu heatsink..

    else enable Vsync.

    I have a CD with older version that came with the GPU but that's about it. But I suspect that it'll decrease my computer performance...

    Why do you say that just out of curiousity?

    In Nvidia control panel, set Power setting to maximum performance, not adaptive.
    Might help alleviate these kinds of issues.

    I already have 4 case fans, one of them directly facing at the GPU, spewing out the air out of the case.

    Vsync is enabled for all games, still causing issues.

    I JUST got the GPU, so no point in claening it
