I was wondering... in regards to performance you have said two things:

The visuals in this game are of exceptionally high grade with slight or no frame drops.

Performance frequently stutters and hitches throughout the quest.

Which is correct?

I've been hearing bad things about the PC port of this game and how it has terrible performance, bad optimisation, stutters, framedrops, constant hitching... part of me wants to buy it, despite it's very high price, but because of these performance reviews another part of me just thinks I should wait til it's on sale and by that time it should have a few patches fixing these things.

Since you've rated it so highly though, I'd say you're not really experiencing these issues?
