Hi ya, Can anyone tell me why there is such a difference in perfomance between the pc''s at my uni and min and my friends. When running DirectX programs on the pc''s at uni the graphics are smooth and not at all jerky. But when I take files to my home PC they become sluggish and terrible to play. I have a 1.4Ghz Pc, 384Mb Ram, 64Mb Geforce2 Graphics card and DirectX 8.1. so I don''t see why the system is struggling. It can easily play the latest 3d games but not a simple 2d space shooter. does anyone know how to combat this?? Cheers Andy

Checked your drivers recently? Might be a video card driver issue. Try downloading the latest detonator drivers from nVidia.

Always remember, you''''re unique. Just like everyone else.

Also depending on how the game handels it''s timing, functions like GetTickCount() can vary widely from machine to machine

It can also depend on the video hardware architecture.
Some onboard video chips set aside a portion of system ram as video ram, which means that if you''re
directly accessing it, it goes at memory speed

If you plot a lot of pixels manually, a system where the data goes across the bus can look jerkier
than if its going into system RAM

I had this problem with a game I wrote when I switched frim cheap onboard chip to brand new ATI Radeon
