Howdy folks, I''ve been programming a typical rectangular tile game (16 bit, 640 x 480), and it works perfectly on 50% of the pc''s i test it on! I can establish no pattern of what version of windows it runs successfully on and what versions it does not. (ie it works on my 98, my bro''s xp, but not my friends xp, etc.) Anyway, the error is basically that it moves incredibley slow and the edges are completely distorted. The Directx version is 7 if that helps. If anyone has any idea what this could be, please let me know. thanks, stilltjack

At The start of your program get the capabilties of the video hardware your program is running on. use GetCaps().
then make sure every feature you use is supported on the card and flag if it isnt(it seems like something is sending it into HEL mode). its going to be one of those proccess of elimation dealys. It dosent sound like an OS problem.
