    lack of speed problem

    I 've done a little game , that runs nicely on a PIII 500 but it's a little slow on my other machine (PII 233) .
    Is there a way to optimise the speed?? I'm using a loop with the timer function.

    There could be a lot of reasons for it to slow down. Probably you've coded something that's just too slow, because I managed to get 72 FPS easily on my p133......

    I don't know how accurate the Timer function is though, I always use GetTickCount().....

    Maybe post some code or more info...

    GetTickCount works basically like Timer. But like I said, I don't know if this'll make a difference, your problem is probably somewhere else...

    Btw, what are you using to draw the game? GDI? DirectX?

    Hey! this is my "first" game in vb!

    So I don't think I'm using these settings...

    I just use to move some picture box with the move function.
    I know this is not efficient...

    I think we found the source of the slowness

    If you're just starting, I don't recommend getting into DirectX. You should try BitBlt (GDI functions). There are a lot of tutorials for it. One of which I can actually remember is Fox's tutorial:

    Tutorial: http://fox.acky.net/english/coding/tutorial/2.html
    Just code: http://fox.acky.net/coding/graphics/bitblt.zip
