Matab is very slow in processing figures: might it be caused by NVidia Optimus?

Hi all,
I have a laptop with the following configuration:
CPU: i7-11850H
RAM: 32GB
GPUs: Intel UHD graphics and NVIDIA RTX A2000
I notice that my laptos is pretty slow especially when managing figures. Indeed, by running bench command, the relative speed is 5.78 (this is the output of bench command 0.8408 0.3923 0.3292 0.6592 6.4034 7.0999) and my system lag hugely with respect the reference machines in 2-D and 3-D performance. When running bench command, the CPU usage peaked 18%. From this data, I believe that my system mostly run with Intel graphics rather on on my NVidia. Is that possible to verify which GPU card is running when Matlab is processing?
Thanks for your help.

Check your laptop's power settings and make sure they are in 'best performance' mode.

Hi Serbring,
In order to see which GPU MATLAB is using you can run the following command:
gpuDevice
The 'gpuDevice' function is the primary way to obtain information about the GPU being used by MATLAB. When called without arguments, it returns an object containing information about the currently selected GPU.
For more information on above function, refer following documentation:

This nothing to do with MATLAB, it is your operating system's graphics acceleration settings. You probably have different power settings than your colleague.
