Thanx,
Is EAX the Creative library ?
I'm still not sure if SDL is the right way for OpenGL wrapping.
I think OpenAL is good for the audio part.
About the timer you're right, i use high accuracy timers.
I meant the movement should generate an event(call a procedure), but if this is not possible you can always send a message if you don't want that speed, messages get quickly to the application you could use a windows timer but even windows has multimedia timers for fast stuff.
