And you're on Win 10? It was running at 90+ FPS in Win 8.1 for me. It's only since moving to Win 10 I've had this issue. Bethesda are in communication with me anyway... they've requested my dxdiag and msinfo32 files, but I don't know what that will tell them. I simply can't figure it out... every other game I have runs fine up to 100FPS.
