My issue began 2 days ago when my steam downloaded the latest 11.5 drivers for ATI. After i installed the drivers all games worked fine. The only difference could be seen in Project Reality.
Black dots kept appearing whenever i moved. The terrain had million black spots all over and it is increasingly and disturbingly annoying.

What i did to fix the issue?
I uninstalled the 11.5 . Restarted . Installed 11.4. Did not work
I uninstalled the 11.4 . Restarted . Driver Cleaned AMD-ATI. Restarted. Installed 11.5. Didn't work.
I need your help with this.
