Okay I isntalled the video driver, which is working perfectly and I have a problem. everything is running slow. browsing folders and stuff is not extremely slow but jittery at times. also when i play chess it just lags and completely stops and i have to force exit on it. My proccesor is p4 2.4ghz northwood with only mmx,sse and sse2 instructions
im running 10.4.8, im thinking it might have something to do with not recognizing my cpu as it is because in the about this mac section it just sees it as unknown and in hardware overview on machine model it says adp2, 1 and not pentium 4 as it should. any help would be appreciated.

Ummm, if anyone could help that would be nice. Everything runs well except sometimes it gets jumpy. Is this because i dont have sse3 instructions? Isn't there a patch that i can get or something?
Thank you

There's a number of tweaks you can try on your machine. Head over to http://wiki.osx86project.org/wiki/index.php/SpeedBoost
for more information - it'll probably be your best bet

I think that reasons are first because of your video card! MacVidia driver don't speed up anything, it just abble you to chose higher resolutions. So all the video lag is because you don't have QE/CI enabled (like Direct3D on windows) because of macvidia driver. Depending of your video card you can try natit/titan solutions to enable QE/CI and so your system will be REALLY speeded up! I made an installer for titan that is working on most of the FX series nvidia cards. Here is the link to the topic: http://forum.insanelymac.com/index.php?showtopic=36044
Second, the fact that your processor only supports SSE2 instructions is a big problem. Emulated SSE3 instructions are not perfect yet and you lose much speed, specially on Rosetta applications! You can look too if your hard drive controller is identified correctly by OSX. If not, the file transfer can be too slow and so the overall system performance too.
