Performance problem

[milin]

Hy everybody! I've got a problem that I just can't seem to fix. I've got a problem when playing Prince of Persia 3 or UT2003, but not while playing some other games like Oblivion! The problem I'm having is that the games I mentioned drag to slow, beyond the point of playing (well, not always but most the time, cca 95%). I do realize this looks like a configuration problem, but my configuration is considerably over the minimum, and recommended (at least for PoP, I do not know for UT). Here's mine and required configuration:

Computer type: HP Notebook nx8220

CPU: 1.73 GHz M --------------------------- 1.5 GHz Pentium 4
RAM: 1 Gb ----------------------------------- 512 Mb
Video: ATI Radeon X600 Mobility --------- Any DX9.0c ATI Radeon from X-family

(other component's aren't vital for the problem - sound card, hard drive space, DVD-ROM drive and OS)

And concerning the drivers, for all component's I downloaded my production company's drivers from the official web page (minus the video card drivers, I got that one from ATI web page, the latest Catalyst, but under the conviction that they are, in fact the reason to my problems, I uninstalled them and returned to HP drivers). I was using AVG for my anti virus program, but like Catalyst, I uninstalled it because I heard form a dozen different sources that it slows the system a lot, so now I'm on BitDefender 2008: Total Security.

So, after this long introduction, what do you think my problem could be?

delete everything in temporary folders, they are useless and use up alot of memery

Unfortunately, that does not help. And may I just say that I'm running the game at MINIMUM video options that is: 640x400 resolution, no effects, no nothing and still it drags disgustingly!

I think you should install the game again.May be that help.Or may be the game has something to do with it.So try it and then tell us after that.

[milin]

No, installing it again does nothing.. And I don't think it's the game it self because it's not just that game..

I've just installed the latest Omega Drivers, and tried running it on OpenGL and Direct3D (minimum settings) but the problem persists! But I've figured out that the frame rate is around 65 constantly! Also, when the game "speeds up", it does not depend on the frame rate - it slows down and speed up on 45fps as well as on 75fps.. I'm getting quite frustrated now..
