it seams when i run more than one task on my gpu it only utilizes around 50% of the gpu regardless of if its 3 or 6 tasks at once. If i run 2 tasks at once it uses around 60%. Running a GTX 4080 and doing All-Sky Gravitational Wave search on O3 1.07 (GW-opencl-nvidia-2) tasks.

Probably using Windows Task

Probably using Windows Task Manager I assume and using the wrong pages for viewing gpu utilization.

Use nvidia-smi instead for true gpu utilization values.
