Hey there, I investigated a bit the stuttering issues on PC with 2 different nvidia cards, a 1660 GTX and a 1050 GTX. What I am calling stuttering issues here are brief moments (~1s avg) where the game stutters dropping FPS then catching up, leading to a brief acceleration right after the stutter. Everything was tested with recent nvidia drivers and on several play sessions to ensure I had reliable and reproducible conclusions. TL;DR: - The stuttering seems split into 2 causes, one of which can be eliminated when disabling the shader cache in NVIDIA settings. - The stuttering is more visible on the 1660 GTX which is also a faster machine than the one with the 1050GTX. But the 1050 GTX is not exempt of stuttering. - The stuttering causes I noticed are: A. Caused when either looking or entering a new light source zone. (This one can be avoided when disabling the shader cache) B. When passing through fixed locations in the game. (Might be zone loading, and I'll assume this for now) - The "story scenes" e.g. when the guardians is landing in the presage mission have fixed 30 FPS on PC, which I believe explains why the stuttering may be even worse there if the scene involves different light sources, like Shadowkeep's "We are your salvation" scene. More info: The presage mission is excellent to play test the issues I've encountered (and also in term of gaming experience, but that's another subject). - When not disabling the shader cache on the GTX 1660, on the landing zone, simply moving to the main big door and away from it will trigger stuttering issues at will. Simply run to the edge of it and then to the door and you'll have consistent stuttering issues near the middle of the platform. - The shader cache being disabled or not, and on both machines but most reliably on the one with the GTX 1660, jumping on the first platform from the landing zone on the left, moving around the corner, and entering inside the ship will reliably trigger stuttering issues. I hope this helps, stay safe.
