I just managed to run a game on linux using wine (Starcraft) and was wondering the following:

How may I give it the highest priority?
Is it possible to close things like KDE and other things like this and just run starcraft?
Also what else may I do to make it more smooth?

I use Kubuntu, playing on a laptop.
edit: somethings when looking more information I don't know what to type to find it mostly of its name similarities with other things e.g. nice command. I don't get what Iam looking for on google.

Thanks

In general, the Linux process scheduler does a good job of assigning CPU time to interactive and background tasks and you shouldn't overrule it unless you know you need to. That being said, the easiest way to increase a program's priority is to use the nice command (see man nice). The lower the nice value the less nice a program is and the more CPU it is allowed to hog. If you want a nice value below 0, you have to be root to set it so you might need to write a little wrapper script to bump up the priority and then start the game as your user.

In general, you're going to need to run X to run Starcraft. If you have a system that's limited on power you can try a lighter window manager like XFCE or Fluxbox as opposed to KDE. WINE itself also probably requires a fair bit of overhead, but I haven't run it in a couple years so that may have changed.
