Initialization Checks

So what do you guys check for when you start your game? I want to just have a small initialization routine just to make sure that if a users PC can't run it to a certain spec then it won't run the game.

Nothing. Let the user dsecide for themselves whether its running at an acceptable speed or not.

I check if the lowest resolution my game supports is available on the user's PC, other than that no checks.

Gotta agree with GfK. Nothing worse than a PC capable of running software, yet refuses to do so because it may not run that well.

At least they get to see your creation, boomboom.
