As donoban also said, Qubes does not yet support high end graphic applications,
but while nothing is official, the keyword here is "yet".
Once the security implications are solved, and enough resources and time can be
allocated to make it work without taking away from the many other much higher
priorities, like security, then we'll likely see high-end graphics available in
Qubes. But Qubes also have really, really high security standards, it will
probably never see the day of light if the security aspect is not solved first.
Which is also *the* reason you can't use high-end graphics or game on Qubes at
the moment. But as you probably noticed by context, this changes if above
issues are overcome.
There are new approaches and proof of concept designs up for discussion, for
example on github, but it's too early to say where all this goes. It does seem
like new proof of concept designs might solve the security issue though, but no
conclusions on this matter can be found yet, not on open channels that I'm
aware of anyway. Keep being patient, and perhaps if we're lucky we'll see this
coming.
