I felt for sure it was unavailable on Debian stable, even checked first, but I made a typo - you’re right, it’s available even there.
I assume you meant CDPR and no, they did not (or to be more precise, they did but it only runs on Stadia’s servers and they didn’t release it). However, there are now tons of people reporting it works with wine+d3vk-proton, both on AMD cards and (more surprising) on nvidia cards. Apparently performances are great (albeit less so on nvidia).
Forgot that witcherino never got a proper linux release. Do folks actually use stadia?
