While Microsoft's Windows 8.x seems poised to break the 25% marketshare mark in the coming months, Valve's initiative to push Linux gaming fails to gain ground. Just 0.86 percent of Steam gamers used Linux in January, a 0.21 drop versus the month before.
TNW processed Valve's extensive breakdown of OS usage figures into a much shorter (than Valve's) combined list as below:Source: Hexus
Windows 8.1: 10.75 percent Windows 8: 10.56 percent Windows 7: 63.04 percent Windows XP: 6.25 percent Windows Vista: 4.30 percent Mac OS X: 3.47 percent Linux: 0.86 percent
Turning to the non-Microsoft OSes, Mac OS X and Linux lost the same percentage of users each during the month: 0.21 per cent.
