Weird bloom problem

[Chaku01]

After installing the latest Omega Driver 3.8.360 (Based on Catalyst 7.4) the weird bloom problem disappeared. The lighting problems and the unstable behavior of my computer while switching shader also disappeared, though on the lowest level there were some new "parasites" (screenshots) visible at a distance, constantly changing while I was moving. All the other shader settings work perfectly now, thanks for the Omega Drivers tip Thomas.
