Thread: Quad Core & FSX

  1. #1

    Default Quad Core & FSX

    I have a Q6600 by Intel and i've tried a "tweak" in the FSX.cfg to use all 4 cores, but I don't believe it makes a difference because I have Vista and the monitor on my cores o the sidebar still shows 1 core being used at most times.

    Is there a way to use all cores?

    The answer to this is probably "yes" but the information is needed to know the answer to your question.

    Have you installed SP1? - Activated use of multiple cores amongst other things
    Have you installed SP2? - Enhanced performance amongst other things.

    If you've added the JobScheduler command and set AffinityMask=15 to the fsx.cfg and you've installed SP1+SP2 then you've done what you can do to use whatever cores may be available. The rest is up to how FSX is coded.

    We detect the number of cores and schedule appropriately.

    The AffinityMask tweak ( in my blog ) is only for when there are problems.

    From: highflightsimulations.com

    FSX SP1 addressed the multi-core issue. There is a fsx.cfg file tweak to set multi-core for FSX operation:

    [JOBSCHEDULER]
    AffinityMask=n

    n= # of Cores

    1 = 1 core 0001
    3 = 2 cores 0011
    7 = 3 cores 0111
    15 = 4 cores 1111

    Just edit your fsx.cfg file and add the JOBSCHEDULER command line and change the n to the appropriate number for the amount of cores your CPU has.

    Go to this website for more information on tweaks
    Great add ons also
    One of the best sites for FSX!

    Ha! So I was wrong in my previous comments to state that FSX doesn't all use all 4 cores if they are available BUT, these are 4 cores running at over 2ghz each...how much better does FSX get? If its still slow....the programming code simply sucks for FSX, lol.

    FSX rocks. on my quad core Q6600 i get 20fps at heathrow and 30-40fps everywhere else with most settings maxed out
