I was trying to run the tutorials provided in the website. I got 2 machines, one with Pentium 400 Mhz and another one with celeron 600 Mhz. When I run the tutorial, they have a very significant difference in speed. Is there a way to control the clock speed? Thanks

no, but there is a way to implement framerate-independent motion. see http://www.gamedev.net/reference/articles/article1382.asp or search the forums.

I believe this is what I am looking for. Thanks for the reply!
