It takes then 2 version (6 months)
6 months?
11.5 = May 2011
11.6 = June 2011
11.7 = July 2011
11.9 = September 2011
Ok sorry 4 months. Is that better? I mean AMD has a broken driver for what feels like forever. The problem isn't subtle. The 100% CPU bug affect AMD own examples in their SDK.
I mean it is impossible not to replicate it.
1) Install 2+ GPU
2) Run AMD own example.
3) Verify 100% CPU bug.
Despite that AMD doesn't fix it and then breaks it further so it ALSO affects single GPU. They finally fix that 4 months later and the fix is limited to single GPU only. AMD can't even confirm if they are working on a fix or that they have verified a problem exists.
