I rolled back to the 15.7.1 too, was working good.
Still hoping for a fix becouse I've seen people talking about a FPS increse, which would be very nice.
Still having the same problem - R9 380 with 4GB VRam (ah, well, it's been only about 2 months... Great). Rolled back to an ancient driver too. I found something weird: there is indeed stutter, but it's almost every time linked to Vsync. Basically, games go from a constant 60 fps to 30 fps. Nothing in-between those two, nothing lower than 30. Deactivating Vsync makes games run at above-60 fps but causes (of course) screen-tearing. I would really like a fix, lots of people seem to have the same problems with the same graphics cards...
clevo p375sm, 8970m crossfire, 4700mq @ 3.6 ghz
massive random stuttering in every game i own (100+)
temperatures dont exceed 65-79° on GPU and CPU (liquid ultra + new thermal pads)
rollback to 15.11 catalyst solves the problem.
please fix, amd
