With Valve's very well known "Steam Hardware Survey", after showing some promising Linux statistics at first, last month indicated that the Linux adoption of the game distribution software was stagnate or on the decline
. The April figures for the Steam hardware survey are now public and they indicate further losses for Linux gamers.
In March the Linux usage was at 1.6~1.7% and now for April it's down to 1.5~1.6% when factoring in all of the different Linux distributions and their diminutive stakes. This is a noticeable drop from around 2% Linux usage when the Steam client first premiered
Hopefully as summer approaches there will be more Linux desktop users having time to fire up their Steam client. Likewise, with Left 4 Dead 2 on Linux being imminent
along with Counter-Strike: Global Offensive on Linux
hopefully in the coming months the Linux use will increase. Having a bigger impact will also be Valve's Linux-based Steam console in the coming months.
