I saw there was a somewhat similar post to this, but I’m kind of celebrating the fact that this was the first year I was able to game exclusively on Linux! I’m very thankful for all of the effort from the people involved in all of the aspects of Wine/Proton, it’s great to not need to reboot to play games.
It is definitely Linux underneath. Technically it says different devices, so that might be why they’re splitting it down. In reality it’s probably a good way to get more advertising for the Deck as people share their stats for the year.
