This method worked well on my dell xps 15 9530 (3200 x 1800) running windows 10, but you would need to be very confident in editing the windows registry and of course backing up and recovering your system files and data should anything go wrong.

Macs will nearly always run smoother and be less buggy than similar or higher specced machines running windows. Although windows 10 is the best windows version so far compared to MacOs it is less optimized because it has to work on a much greater variety of machine configurations and software.
