GPU-tasks do not verify how many CPUs are used

[michel83]

When a system uses 100% of the resources available, the performance of the GPU tasks may drop significantly. The GPU task does not check how many CPUs are already in use, so that eventually more CPU time is needed than available. (Example: System has 6 CPUs, all of them used by a task, the GPU needs an additional 0.5 CPU).

Using the Preference Settings and limiting the CPU usage to less than 100% is possible but it would be more accurate and convenient for the user if the system would check and adjust it itself.
