Symptoms

Stutters (sudden quick heavy frame drops) when entering and exiting cut scenes (for example, when interacting with a character like Adam and the camera is not in the "playing" position, you can still tell it's in-game and not a pre-rendered cutscene).
Also after loading screens like entering a different area (for example XION, EIDOS 7, or any other area that requires a loading screen), after 3-4 seconds of loading, another stutter like the others mentioned happen.

It's weird because the game otherwise runs impressively smooth.

The error happens over and over, it doesn't go away after reproducing it one time. Same interaction will create the same stutter/FPS drop.

Reproduction

Play as normal, interact with characters who give camera-altering animations/cut scenes and/or enter loading screens like when loading maps.

Start with the attached steam-3489700.log and the linked full system information report, then reproduce the repeated stutter in Proton Experimental during camera-altering interactions and after loading screens. No source file or test is named; completion would require identifying an actionable cause and verifying the reported reproduction no longer produces the frame drops.
