Low FPS in viewport of UE5

Currently my system is Nitro 5 with i7-8750H, 16GB RAM and GTX 1060 6 GB Graphics card, The UE5 viewport lags too much only getting like 5-10 fps. Tried multiple options like disabling lumen, disabling nanite, shadow maps, etc. nothing worked.

And also when I looked into the Task Manager UE5 is not consuming the GPU. only RAM and CPU are used. Any help is appreciated.
