I always try new drivers, beta or not Then again, I'm not worried about crashes and etc. sice I have a backup disc and add a system restore point before installing drivers. Perhaps it's because I'm a tweaker, and is curious if new drivers gives me better performance!
Also when concerning the Radeon card, all new drivers have to better than those they provide now The card lacks some good drivers that gets better quality (blending, smoothing and such) on graphics in games!
Existenz, I could not get the ATI XP drivers for my All-in-Wonder Radeon to install either. I sent an e-mail to ATI and even tho it took them over 2 weeks to respond they did provide some detailed instructions that did work. I think it was mainly installing the latest Via AGP driver properly that fixed my problem. Now I just have to figure out why the DVD 5.0 will not work
If you are interested in what ATI said to do just give me your e-mail address and I will forward it to you.
Did you check to make sure that all your BIOS settings matched the ones that they had listed? Even if you dont think some of them look right it doesn't hurt to try them. I also installed the latest AGP drivers from Via before installing the ATI drivers.
