I will load up a save and be in a tavern. Just standing there no movement at all. Framerate at 60-70fps.
Tick tick tick tick.. per second, the framerate just ticks down, 59, 58, 57, 56.. all the way down to 35-40. Close to menu. Reopen, same spot - back at 60-70. Then ticks down again. Its super weird.
Some cards lower the clock when suffer from high temps. It's a security feature. Can you check your cards Mhz when the FPS goes down? Are the Mhz going down too? Are temps high when the fps drops begins? Or try to disable hairworks from options, in some cases shows weird beheaviours...
