As well, EV’s lose very little of their energy to heat or other losses between the battery and wheels unlike ICE vehicles. The result is drag plays a more significant percentage of where the energy is “going”, so the impact of higher speeds on range is greater then it is for ICE vehicles.

The game is probably CPU bound not GPU bound, based on past bethesda games. If that is the case, decreasing the resolution will not necessarily increase the frame rate a proportional amount.
