    Like most users, I update to latest drivers.... Nvidia doesnt support, so i turned to dells new beta driver..

    186.12

    With this driver set, Ive noticed FPS drops to 5 frames a second randomly couple times a minute within games.


    FPS Stutter:
    Demigod
    Call of duty World at War

    No FPS Stutter:
    Supreme Commander
    Left 4 Dead

    Currently rolling back drivers, to see if issue persists

    gabeZ also reported the issue with COD 4 ... we think it is a SLI lag/issue....with the new driver ...

    needs more testing though

    Still doing it... even with the rollbacked drivers... this is not good,
    Is there a way to turn off hybrid sli, or is all video going through the 9400m ?

    I also found that attempting to remove/rollback to the old drivers doesn't work to well. I actually got some graphical corruption when I tried..... ultimately ending in a system restore. The slow FPS spikes in Call of Duty 4 happen with the stock drivers as well.
