My build
So, I get these weird stutters on ESO, they are not consistent but I'd say they last for like 300-700ms each and happen every few seconds for a few minutes. They eventually even out.
I also get a very weird fps range, when I first start the client it's locked at 100fps, then in game it's around 60, but when this stuttering happens it barely makes it above 36fps.
Restarting ESO fixes the issue entirely and fixes the FPS too, or at least until it starts back up again.
I am not sure how long it takes for the issue to start up after a clean launch, but I don't really close ESO often.
Any ideas?
