    Graphic problems with Dual Core processors

    Hello, I have problems with an application which draws some graphic on the screen on a new laptop I have, and this seems due to the new "dual core" technology. I heard rumors of graphic problems in other applications: does someone know something? Is there any "utility" which permits to use the processor in a "legacy" way?

    Thanks,
    BrownB

    From task manager, click on the processes tab.

    Right click on a process and you should see "Set Affinity..."
    Choose which processor to run the process on.

    This affinity is "sticky" in that any process which the modified process spawns will also be locked to that processor.

    No doubt there is an API call to achieve the same thing.

    There's also a command line tool to manipuate this, but it's name escapes me for the moment.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    If you get some problems, just do as Salem advised you to do.

    Some games are 2 times faster because of dual core, but most of the games are not affected by it.

    Setting the affinity worked great, that was the problem. My application isn't using correctly graphic threads, so using Dual Core (as in the past using HyperThreading) causes the two graphic threads to be not executed in the right sequence. I must go down in code and manage this, but before this I'll use this solution.

    Thanks a lot!
