Hi, thought I ask here as it seems like the place where the most reasonable discussions go on. Did a quick search, some people get freezing but I don't know if this is quite the same thing?

So in a nutshell, game runs super smooth on start up. In what ever area I start in.

As I play the gamethe frame rate gradually drops, eventually becoming a slide show. I think it may be linked to new areas loading in and old ones not unloading? The end of act Ii was particularly bad as there was quite a few different areas in rapid succession. At the moment I'm just saving and restarting to fix it, but I don't think this is how it's supposed to be.

Settings are
Borderless windows
Vsync off
The fidelity is whatever the game started with, haven't messed with any texture, shadows, dlss or anything of that nature.

Any help would be appreciated.
