Recently Brian Burke fomr NVIDIA asked for help in the NV News forum. Now he has some news about the flickering issue :
We had one person in the Bay area confirmed with these symptoms. He was kind enough to agree to visit us. We had him come in to the NVIDIA offices today. We were able to see the “flicker issue” and try some things to fix it. We have some good theories about the cause. Next step is to reconstruct his system, prove our theories, and then find a solution.
We will let you know when we have some definite conclusions.
Thanks to all for your feedback and help in resolving this issue.
