[gameprogrammer] Re: random speed up

Wow you hit the nail on the head, that does indeed happen - each time
i go to the main menu then back into the game it goes faster and
faster.

It's strange because i'm not messing with the CPU priority or
anything...as far as i can tell the only thing that is happening
(apart from what say...fmod might be doing) is just loading and
unloading some textures, and allocating/deallocating some memory.

Do you think fmod could be causing this?  Having never hit this
problem before, how do you release the cpu back to the os, just set
the priority to a lesser value?

Thanks a lot for your help!
