Yeah. The mesa portion is a little messy since the extension isn't registered yet. But it can be found on the wip-high-priority branch here: https://github.com/lostgoat/mesa.git For a test app you can download this other project (wip-high-priority branch as well): https://github.com/lostgoat/Vulkan.git Once everything is setup I run one session of the SSAO sample: QUEUE_NUM=0 ./ssao Then you can simultaneously run the computeparticles with or without high priority: sudo QUEUE_NUM=0 nice -n 20 ./computeparticles -high-priority Or sudo QUEUE_NUM=0 nice -n 20 ./computeparticles Note: QUEUE_NUM is required. If you have any issues building/running these let me know.
