I only use a late version of the open beta on a LAN session with friends two or three times a year and we play the game from one up to three hours without issues or crashes or stuttering with pure wine on arch Linux.
There was a recent issue in wine where the game didn't start anymore. That happens from time to time, things break and get fixed again.
It's fixed already, but not released yet.
I sometimes have an issue where I cannot look left to right more than 90°. Here it helps to toggle mouse warp in wine. Strange, but for me that seemed to help.
This is what I consider pretty payable. There are other things like anticheat that causes trouble. In my experience the Renegade X open beta worked pretty well.
I remember a later version of the beta didn't start anymore. Here I don't know if that also happened on windows, too. But that also happens. There are many reports I found for windows while I searched for a Linux issue and found out that it is just a general issue everyone has, no matter the OS.
And yeah of course games do not run as great on Linux than on windows. They are made for windows.
My intent is to say that for me this game is not a bad experience on Linux.
Good luck.
