Processes on my Ubuntu not using the NVIDIA GPU despite being slow

Hi,
I just dual booted my device, windows 10/Ubuntu Linux 20.04 and all went smoothly. I tried to run Carla simulator and it was incredibly slow despite me having hardware requirements. I have tried numerous advises and solutions but to no avail. nvidia-smi is reading the GPU but shows no change in processes nor memory usage.

Please help me with this issue as it has puzzled me for too long. Thank you and appreciate your time!
