Microsoft's divisive Windows 8 platform has become a more popular operating system than Apple's Mac OS, according to new Steam survey data.
Despite Valve managing director Gabe Newell branding Microsoft's new platform a "catastrophe", about 4.6 per cent of Steam's customers now use the OS.
By comparison, 3.3 per cent of Steam users play on Mac, while 8.1 per cent use Vista. Most popular by far is Windows 7, which is used by 72.6 per cent of Steam's survey respondents.
Valve's Steam platform has more than 50 million registered users.
The Steam operating system market share results follow:
- Windows 7
- Windows XP
- Windows Vista
- Windows 8
A growing collection of games developers have spoken out against Windows 8.
In September, Mojang co-founder Markus Persson said he would "rather have Minecraft not run on Windows 8 at all".
His statement was made in the wake of comments by Valve co-founder Gabe Newell., who triggered the debate in July by declaring Windows 8 "a catastrophe" for people working in the PC space.
It is believed that Newell's specific concern is that the new OS could lead to content update filtering by Microsoft, which in turn could bottle-neck updates on platforms such as Steam.
Microsoft is unwilling to publicly discuss such claims about Windows 8.
