Since I've been playing around my valley scores are about 50 points lower. I've tried reverting drivers, going back to beta drivers, disabling igpu, changing bios back to original and back, closing everything in the background...my stock scores won't go over 2600 (maxed at 2848 before) and my overclock scores are all in line with that.
Kombustor might also be affected, but firestrike and heaven are not.
Haven't tried uninstalling afterburner, I guess. I've deleted the profiles many times however.
