Yes, on PC you have to do some trickery to maintain stability if you don't have a fairly powerful PC. I've tested the beta a bit and well, I don't love having to resort to things like frame generation, but after doing several hunts and not feeling problematic input lag, I think I'll end up buying it when it comes out.
Supposedly they have improved performance for the full game, but personally I doubt that improvement is substantial.
