It does not matter how I exit the game (as I've tested this many times), Rust will 90% of the time drop my main graphics setting to the lowest.  Anyone else have this problem or a fix for this?

Same problem here

I also have this problem but a friend of mine doesn't have that problem at all, he has a 1050 Ti, do both of you have amd gpu?

I have NVIDIA GeForce GTX 1060 6GB

I don't understand why this only affects some players and not others.

ya same here..
