lack of speed problem

[trasher]

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...

How should I use getTickCount ??
what this api does??

[PsychoMark]

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...

[trasher]

Is there a better function?

How Can I use directX or GDI ? (THAT's the question! hehehe)


p.s. thanks for helping me!

I think we found the source of the slowness :D

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:
