For those curious about people on "lower spec" computers -
Ryzen 5-1600X
32 GB DDR4-2666
Gigabyte GeForce 1080
Tearing is terrible.
Crashes every 2-30 minutes, completely randomly (happens during play, when in menus, when on pause menu, etc.)
Generally I can expect about 3-4 crashes every two hours on average. They are all total game-killing crashes.
I've done everything I can think of and have found on forums/videos to improve the video. Generally it's tolerable. No idea of my framerate (I'll measure it next time I try to play)>
The largest issue is the consistent CTD.
I think it may be a VRAM issue. The 1080 has 8GB, and my friends with 2080's are not having (as many) issues. One is having about half as many crashes as I am, the other has had no issues.
