They are just unfriendly to players wallets

The Linux version of the game is sometimes treated like an unloved stepchild though. I actually played the game through Wine for years because the Windows build had about twice the FPS on my Linux system.

There's also a bug when reflections are enabled that makes the game unplayable and it hasn't been fixed for about a year. It took them something like two years to fix another one where the mouse randomly left the window on a dual monitor setup and that one basically made me stop playing altogether. That said, I appreciate them supporting Linux in any case.
