I just thought I would share my experience so far with the Linux demo since it is experimental. So far I have had no crashes, glitches or any problems at all. I'll play a bit mroe but so far so good. I'll be buying a copy on release. Thank you for the Linux version and the DRM free version. My system specs are:
AMD FX-9590 | 16GB DDR3-2133 | MSI RX 580 8GB Gaming X | Mesa 17.2.5 |Samsung 850 Evo 250GB | Solus Mate 64 | Kernel 4.13.16-35.
