for example look what happens in 15:54
as you can see it doesnt only happen to me. game is butter smooth when first load it, but it degrades over time. reloading saves makes it degrade faster.
most noticable is the amount of stuttering when you move the screen around, compared to start of the game.
that video is not a memory leak issue.
there's a fundamental inefficiency in the game engine. I think it's related to some operations being done synchronously instead of asynchronously, or poor job scheduler management. The reason why the game lags in that video there is because a ton of resonant touches are being processed, and it does in a way that is characteristic of poor threading or job scheduling - it tries to do it all at once, in conflict with trying to render new frames of graphics or processing other game logic.
this happens with a bunch of similar other effects - before I gave up on nvidia 2080 ti (due to constant RMAs) i had a beast of a machine that i built a few months ago, but even then if i cast mirror image the entire game would seize up for a split second, which to me sounds like just way too much work being done on the main thread no matter how much hardware you throw at it. this is true whether or not mirror image was the first thing i did from a cold boot, or i had already been playing for a couple hours.
there are issues with quickloading not completely "cleansing" game state (resulting in various bugs over the life cycle of this game), but it should not be resulting in memory leaks.
also, i would possibly raise the issue that if you're experiencing slow downs as the game goes on, that you're experiencing throttling on your hardware due to insufficient heat dissipation or something. Before I built my new PC I had a 6-ish year old CPU with an ancient intel cpu, a gtx 1060, and like 8 gigs of ram and didn't have any kind of slow down over prolonged play.
edit: also try turning down graphics settings. glow and lighting settings add a lot of graphical overhead. my current system (now using an amd vega 64) can run fallout 76 almost perfectly at 4K-max settings, but I still have to turn off anti-aliasing and settle for consistent sub-60fps on Deadfire at 4K (dropping into the ~20-30fps if I have more than one wall effect active). Unity just gives you a less optimized experience than other game engines.
