Please consider putting resources towards Linux support. I am a Tobii 5 customer and use it for gaming, but kind of regret going with this product because it doesn’t work on Linux at all, which is wild in 2023. Over the past few years more and more games have gained great Linux support thanks to Valve / Steamdeck & proton.
I use Tobii primarily for Star Citizen, and SC runs well on Linux, so really it’s just Tobii keeping me tied Windows at this point. Track IR can work on Linux apparently so starting to look into that, even though I much prefer Tobii’s approach to tracking.
