The Linux version works. It has been suffering from a problem that affects the Dead Island and Dead Island Riptide definitive editions as well, since some version of the Nvidia driver, but there’s a perfectly effective workaround.
Workaround : As per the documentation in chapter 11 of the Nvidia driver docs (on Ubuntu 22.10 with driver version 515, check this file : /usr/share/doc/nvidia-driver-515/html/openglenvvariables.html), you have to set the __GL_IGNORE_GLSL_EXT_REQS environment variable to 1, so that the GLSL extension checks errors are ignored.
On the Steam client, you have to set the launch options to :
__GL_IGNORE_GLSL_EXT_REQS=1 %command%
To be honest I didn’t try for Dying Light yet, but I’ve read that Dead Island Definitive Edition and Dying Light have the same problem, and it works on Dead Island, I can confirm that.
So yes, it works on Linux. Imo, Techland should have given us a Linux version no matter what, and a Galaxy-enabled one later, for the Galaxy diehards.
For the impatient (like me, though at that point, I’m not sure “impatient” is the word), there’s currently a big sale on Dying Light and other Techland games on Steam.
