Bob. We just suffer with them not updating drivers on certain setups like my AMD APU. Can't get any updated drivers for it. But after reading all this. I was surprised to see this from Nvidia.
Read this:Link you'll be surprised further more..
Well yeah thats a BETA thread so yeah there will be problems with using a beta driver :P
Didn't I advise you to use the older drivers until a stable one is released?
Beta is not necessarily less stable than Whql and this Beta is much stable than all the older drivers, the last Whql's had more than 60 pages of complaint posts before they were deleted due new Beta driver.
Beta drivers are not 100% stable, hence why they are beta for testing with others so they can pinpoint potential bugs for the next full driver release.
I think some of you people are gluttons for punishment :P
Whql are far from 100% stable and like I said the latest beta is the most stable driver than all the predecessors.
