Oh - and another interesting stat, the number one OS is still Windows 7.
From what I've read it was a recent uptick in Win 7 usage that bumped 7 up over 10 and that Win 7 is still the most popular OS for gamers. Will the uptick hold? Grow? Or fall off again (as expected)? Most analysts believe it will shrink again and eventually fall of to maybe 29% by 2020.
I can't imagine ANY gamer wanting an OS that updates whenever it wants, each time possibly screwing up something that makes a game(s) no longer work, or work improperly.
Gamers use PC's with specific mother boards, processors, after market video cards and hardware accelerators etc. It is not "if" but "when" would a Win 10 midnight upgrade come along and suddenly your video card won't work and you cannot roll back the upgrade...so go good luck getting that fixed.
I would imagine Dell and company are well aware of all of this and must be doing something to keep gaming PC's on a more static OS.
I wonder how you fixed the gaming issue on Ubuntu or Mint.
It isn't up to Linux to "fix" gaming. They have no ability to do that. There has to be a valid commercial reason for game makers to port to Linux.
Valve has stated recently that they haven't given up on SteamOS, but it isn't up to them. It is up to gamers and what they buy.
Windows 10 has thrown a potential wrench in the PC gaming field. Obviously. And that is why gamers use Win7. But that cannot go on forever.
The only answer MS can have is to make a gaming OS, perhaps they will.
Linux has, and always did have a platform that can work very well in the gaming field, indeed better than Windows since it does not use half the resources of Windows...but why on earth would game makers port it to Linux with such tiny marketshare?
The OS's abilitiy has nothing to do with it.
