POSSIBLE SPOILERS
The game’s been performing decent-ish (dips to 30FPS due to V-Sync every now and then like during the ice/fog parts or looking at radiation liquids) and everything was fine at this part of the level until I loaded it up lately to continue.
It’s the part where the assassin/stealth soldiers are first introduced when they kill the guard trying to relay a message. As I approach the hangar area where they’re all at, the game goes from 60, to 30, to 15, to 10 and below as I get near or into the hangar.
A few days before this started happening everything was fine, now recently it’s been acting up like this. I have tried lowering settings, turning off V-Sync and even did the affinity/priority Task Manager fix and it’s not doing anything.
