Microsoft Flight Simulator PC Performance Review and Optimisation Guide

Resolution Scaling – Faux-K VS 4K  

Resolution Scaling is a common feature within modern PC games, offering gamers the ability to sacrifice a pixel-perfect resolution in order to free up enough GPU performance to enable higher framerates and more stable performance. 

With Microsoft Flight Simulator being such a demanding title, resolution scaling will be a must for most PC gamers if they are using a 4K screen, forcing gamers to sacrifice sharpness for the sake of increased framerates. 

Below is a screenshot comparison between a 100% (native) resolution scale and a 90% resolution scale, using images which have been cropped from 4K images. You should be able to see a sharper image with our 100% image, though a 90% resolution scale offers such a minimal quality sacrifice that the performance benefits are worthwhile.

At 4K Ultra settings, Resolution Scaling can be used to significantly increase Microsoft Flight Simulator’s average framerates at 4K, though at resolution scales below 80%, we start to hit CPU-related performance limitations. High settings with an 80% resolution scale should keep an RTX 2080 Ti’s average framerate over 60 FPS.
