Same here. I’ve only a Linux machine for over a decade but I had to go out and buy Windows just so I could play on FaceIT. I’m praying that cs2 supports Linux and the MM experience is good enough to make FaceIT obsolete.
Buy windows?
A Windows license is in the realm of $200
I don’t want to encourage Windows usage, but if you really need it you can buy a grey market license for $10-20.
