Valve have put up their usual monthly survey and the interesting thing for us is that the Linux share is the highest it's been for some time now.
We're currently tracking it every month on a dedicated page which gives you some historical data. As you can see, the current Linux market share on Steam is now at 0.71% as of September's figures. It hasn't been that high since July last year when it hit 0.74%. Although we're still chasing that elusive 1% mark.
With Valve introducing their new Steam Play system near the end of August, it certainly seems to have had an effect. Whether this continues or not is certainly going to be interesting to see, but it's still a pretty good sign. Still not exactly a high percentage when you compare it to Windows at 96.30% for September, but we do have to remember the seemingly ever-increasing user-count on Steam too which means we probably have a lot more users than some would think.
The biggest uncertainty will be people testing out Linux for Steam Play, if they do decide to become fully-fledged Linux users. I've honestly lost count of the amount of people across the net, that said they've officially dumped Windows or they're finally trying Linux out. There's been a lot of positive talk about it lately, so no matter what Valve have put Linux back on the radar.
