Hi, i would share the solution which worked at least for me. Maybe could be useful for someone else.

After check my system all appears to work correctly but the issue was still there.

So the next step was an update of GPU drivers on a clean installation. Now the game works nice for me, no lag, no agonic loading times and fps into city 30, on field 60-70.

For all who play with NVIDIA GPUs try to update your drivers including the beta versions if dont work the others.

This works for NVIDIA Geforce GTX 465
