Just look at the google search results for this issue.
This issue is widely reported, I just talked with AMD and they indicated it was a known issue, and that the issue exists on both AMD and Nvidia platforms. They said they were in communication with Blizzard to fix this issue.
So my question is why isn't Blizzard stepping up and helping resolve this, this issue has been ongoing for almost a year.
The only fix at this point seems to be dropping down to DX9, which sucks considering we have $500 video cards that we cant take full advantage of.
Any chance of a Bluey responding to this?
