Windows 10 has become the most popular platform for PC gaming. The 64-bit version dominates usage.
This is easily reflected by the users on the site. XP has now faded near obscurity with less than 1% of users. Windows Vista never took off with gaming and Windows 8 was a mess until the 8.1 updates cleaned it up.
The PC gaming market is more than double thes size of all consoles combined.
