PULSE_LATENCY_MSEC=100 PROTON_LOG=1 LD_PRELOAD="" %command%
Crackling fixed with PULSE_LATENCY_MSEC=100. Other review mentioned 25 instead of 100 but I needed to bump it up to 100 milliseconds to avoid it altogether. Fortunately, I did not notice any audio desync with this option on.
In some areas of the game (I counted 2 places total) there would appear large black squares covering a quarter to most of the screen, and would follow camera movement. This only happened in 2 small isolated spots in places that probably had a lot of shadow/lighting math going on.
After anywhere between 10 and 40 minutes of playing, the game would suddenly switch from smooth 50-60 fps to capped at around 20-25fps, and no in game setting modification or waiting would fix it, requiring a game restart. This was fixed with the LD_PRELOAD="" launch option. See https://forums.linuxmint.com/viewtopic.php?t=434190 for more details.
After initially backing up to proton version 4 and 5 after an early startup crash like was mentioned in other reports, the game could not open my existing save data from when i played on windows. I thought that this was an actual issue, but jumping back up to proton version 7 fixed the issue.
