Kibou: Judging by the version number of the driver, I guess you've got an ATI Card, and you use the official Catalyst drivers?
Can you tell us which video card exactly you're using, and which driver version made the bug appear? This might be useful information for other users in the future. Thanks in advance! :)
Sure, was using a an HD4850, with 11.6 Catalyst drivers. Reverting solved the problem, however, the 11.5 drivers give a bit of microstuttering, while i managed to get rid of most of it in 11.6.
Still using 11.6 CAP2 with 11.5, and works fine.
