Madhi19 Reddit new post madhi19 on CS:GO just updated a large number of systems necessary for the Linux client.

It also only the very last* game that valve had to port of their rather large catalogue. Frankly I rather get L4D3 day one on Linux than another version of Counter-Strike sooner. *Not counting L4D1 that they never planned on porting.
