An anonymous reader writes with news that Valve has updated its Hardware & Software Survey for December 2012, which reflects the first month of the platform being available for Linux. Even though the project is still in a beta test, players on Ubuntu already account for 0.8% of Steam usage. The 64-bit clients for Ubuntu 12.10 and 12.04.1 showed about double the share of the 32-bit versions. MacOS use also showed growth, rising to about 3.7%. Windows 7's usage share dropped by over 2%, but balanced by the growth of Windows 8, which is now at just under 7%. The total share for Windows is still about 95%.
