DavidC1, Which of the resolved issues in 5273 do you expect to take care of or alleviate my reported problem?
When I attempted to install the XP 32 bit, I received the message: "The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer. Setup will exit."
Edgar, try the solution I have in this thread:
I can't be sure it'll fix it, but on the Windows 7 driver version it notes the problem of "some shaders taking long time to initialize" was fixed. Though that wasn't said on the XP driver, they both share certain rendering paths and may help you.
