I'm running a single 7970 and have been trying to iron out some issues I've been having recently. At this point I'm thinking im getting microstutter, but I don't know how to properly identify it. In battlefield 3/4 I get 100+ fps constantly but lately it feels more like 30-40 at best and the gameplay is far from the smooth experience I'm used to. It does sometimes run smooth but in the past month it's been very hit and miss.
