OS affecting GPU performance?


Jul 31, 2003
I´m on a dual OS system (Windows ME & XP Pro). When using the latest WHQL drivers from nVidia for both OS, I get 400 points more when running ME in 3Dmark, and the general gaming performance is much better.

I´ve optimized XP for performance, removed indexing, restore, auto-update and tweaked the Services, what more can I do? Right now I´m using XP for surfing the net and Office, and ME for heavy online gaming.

What is wrong here, should ME really perform better in games than XP Pro??? I love XP and would like to use it for everything, but for now ME is much faster in games... I know XP is more future-proof, but for now ME is much faster in the games I´m running???

P.S. Using games like BF1942, Medal of Honor, Sub Command, ST Fleet Command 3, SeaDogs, POTC and Civ3 - Play the World.

The difference between theory and practise in practise is greater than the difference between theory and practise in theory.<P ID="edit"><FONT SIZE=-1><EM>Edited by Praesul on 08/13/03 07:25 AM.</EM></FONT></P>

What's your video card, your cpu, your ram, your motherboard? some system specs could help. The reason I say this is that xp likes a lot of ram. If you're heavy into gaming and are using xp, I would wager a guess that you should have at least 512 megs of ram. If you only have say....256 or less, than this might be one problem.


3dmark 2003 or 3dmark 2001 SE?

A 400 point difference in 3dMark 2001 SE is not noticable and not worth pointing out.

A 400 point difference in 3dMark 2003 is pretty substantial, though...

Toms Hardware had an article showing gaming under different OS's. It said that ME was the best at gaming and XP was only a frame or two behind. I found this to be the total opposite on my system. I gained 500 points in 3D Mark 2001 when I changed from ME to XP Pro. Just make sure you have the newest drivers. For 3D Mark 2001 SE the best drivers for Nvidia are 40.72.
