Did you try on Linux? Most FreeBSD graphics drivers are ported from Linux.
If prioritizing certain GPU workloads (e.g., OpenGL) isn't supported on
Linux then I don't think FreeBSD can manage to do better.

What about NVIDIA? OpenGL stutters if CUDA (via linuxulator) is used at
the same time. I've tested on nvidia-driver-375.66 as CUDA apps crash on
nvidia-driver-384.59.
