It's not that, I've experienced these issues the OP is talking about, but ever since I got my ps4. There are times where if you're looking at a certain direction, popular or not, the FPS dips really low. To me it happens when I look at WhiteBrim when I'm on the north side looking south. It also happens at the snow cloak entrance. I have no idea why it does this, and it doesn't seem to be a hardware issue (my ps4 isn't overheating, fan noise is minimal).
