If prioritizing certain GPU workloads (e.g., OpenGL) isn't supported on Linux then I don't think FreeBSD can manage to do better. > TL;DR when the FreeBSD GPU driver and all the userland bits are up to > date, I'd expect there to be no issues with stuttering. 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.
