  • DOS window using all cpu

    From Daniel Path@2:371/52 to All on Fri Dec 19 11:29:58 2025
    Hello All,

    some of my door games (for example Kannons & Katapults) eats up all the
    CPU in a DOS session. the game runs great, but after a while it starts to kill other os/2 processes (Xenia Mailer!).
    Is there any setting like nice to limit CPU usage in dos sessions? or
    do you know other tricks?

    my SESSION_PRIORITY is already set 1.
    and yes i've tried the newest shiniest and brightest Kannons & Katapults as well, but works the same :(

    There is a tsr program to run in dos session called OSTSR. You could try it. I was using it when running a dos based bbs (SuperBBS) under OS/2 once in the past.

    Freq OSTSR12I.ZIP here.
