I see lots of responses from the Dev team about Linux not being supported, but I will add my 2 cents. Linux support is leaving out quite a few enthusiasts in the market. many of us spend thousands on Star Citizens (concierge) to get the ships and experience we want and are definitely willing to invest in eye tracking technology for a decent price.
Again, adding myself into this conversation to show interest in a linux API or software support for Tobii eye tracker 5 support.
