Hey there,I just reported this using the link in AMD Issue Reporting Form post. Just want to know if anyone else having problems with new drivers' performance in C++ AMP?Switched to Catalyst 12.10 (9.002 driver) and the performance of the C++AMP applications got three times worse, from ~5 ms using Catalyst 12.8 to ~15 ms using Catalyst 12.10; when I changed to 12.11 beta it got worse and up to ~35 ms.It was fixed the moment I changed my driver to the one on Windows update (named AMD WDDM 1.2 driver for Radeon HD6000 series) but now I can't use Catalyst Control Center !Usually I don't use Catalyst Control Center but it's somewhat frustrating to see the performance worsened 3 to 6 times using the new drivers.Anyone else experienced this?P.S.: honestly AMD people, dont you guys test these drivers before releasing them?
