Linux build runs... but has an abysmal and unplayable frame rate on my computer. Couldn't find a graphics quality setting to change the resolution or quality to see if that would help. What was odd is that CPU usage was only at about 50% of one core, so it wasn't CPU bound and the graphics don't look like something that should make my GPU choke (maybe there is, I just have the integrated intel graphics that is part of my 7th gen i5).
Thanks for trying on the Linux build!
