Absolutely. Absolutely.

Those won’t fly. Those won’t fly.
We do not provide OpenGL virtualization for Qubes. We do not provide GPU virtualization for Qubes.
This is mostly a security decision, as implementing such a feature would most likely introduce a great deal of complexity into the GUI virtualization infrastructure.

However, Qubes does allow for the use of accelerated graphics (OpenGL) in Dom0’s Window Manager, so all the fancy desktop effects should still work.

AppVMs use a software-only (CPU-based) implementation of OpenGL, which may be good enough for basic games and applications.
