There's nothing else I use Windows for that can't be done as well through a xen vm.
Do you run BF4 like that?
He could. I don't run BF4 like that because I have no interest in shooters, but my xen vm can run any game you throw at it.
Indeed I could, but it'd require a somewhat radical reconfiguration of my partition layout. I'd do it in a heartbeat though for the remaining Windows only games the second I knew I could play my primary games natively on Arch.
You can switch to LVM. much more malleable

The whole history about no games on Linux/only DirectX thing was pretty funny. Or very facepalming depending on your perspective.
Someone who actually works with OpenGL regularly probably knows it better, but it sort of boiled down to Microsoft making sure their new DirectX 8+ API was a lot more open and accommodating to game programmers wanting to code for GPUs, particularly when it came to hardware cross-compatibility and coding backwards compatibility, than the mess OpenGL implementation began to turn into. Previously, MS were publicly slated multiple times by all the industry bigwigs since their previous attempts in making Direct3D usable were terrible to say the least. It wasn't like no one cared about OpenGL either; Nvidia loved it to bits and pushed hard for it, even after MS basically gave them free reign on implementing shaders.
And even then, the OpenGL people probably had at least 3 separate opportunities to trump DirectX to the limelight since win2k, the most recent being the whole DX10 on Vista only thing, only to derp up every single time. The irony is D3D has evolved into what they intended OpenGL to be, proprietariness aside.
And how is DirectX more open than OpenGL? You are forgetting that DirectX is only available on Windows. One of the main problems in the PC desktop is the lack of interoperability between Windows and other OSes. If Microsoft would make DirectX open source and cross platform you would see more gaming support for Linux.
Given the marketshare of Windows and that Microsoft owns the rights to DirectX so MS can make it exclusive to Windows thus preventing interoperability, that is why MS STILL has a monopoly in the PC desktop.
