Some graphical tasks are quite slow and/or require a lot of CPU resources. I guess this is because AppVMs use a software-only (CPU-based) implementation of OpenGL. It seems one cannot do much about it, since it’s necessary for Qubes OS GUI isolation. Related issue .

Depending on the hardware, GPU passthrough could help.
