RTX8000 utilisation at 25%, with frequent hangs

Hi I have successfully now run GPU based application using WSL2+CUDA however the average utilization has been at 25% as per ‘NVIDIA GPU UTILIZATION’ viewer this somewhat not reflected in Task Manager which shows 0% utilization.

However, in the Task Manager, the maximum ‘Dedicated GPU memory’ given to WSL2 it seems is 24.6/48GB.

this is done on 4TB SSD, 256GB RAM and 20C PC

Is there something limiting the full utilization? There are also hangs where GPU drops to 0 with 100% reading on SSD

Any help is appreciated
