How can I run it to perform the GPU?
Leon explained this over in his comment on the other thread here: TorizonCore 6.1 cannot render anymore 3D content on Verdin iMX8M-Mini - #58 by leon.tx
You need to install gputop in the same container as the process you want to measure otherwise it won’t “see” the process and give misleading results.
