I meant to un-install dx 9:0 and re-install it again, or even a previous version of dx.
It doesn't say it won't work with some games or that it's slower than other cards, they will just say that benchmarks arn't accurate or something else.
The best way to install any drivers in win xp is to go to System,Hardware, device manager, then click on display, right click on the graphics card and select properties, from that menu select update driver and choose the location browse to the folder you created for the downloaded drivers and select that folder.
Don't let windows search for the best driver, it seldom works properly.
Also I always un-install the old drivers first then re-boot, then when windows detects the new hardware I cancel that, and do as I said before.
I selected the performance drivers, but you can try both if necessary.
