Please calm your tone, I already feel stupid enough for not having 15.7.1 :unsure:. After updating, it did alleviate a little bit of the performance problem, but I am still getting a little bit of stuttering and buzzing from my GPU. I am also using DX11 by the way.
Sorry, I sounded too harsh - I was partly mad at myself - as for stuttering - the rest is the Pentium's fault. Dual cores are dead.
