Together with the publication on Xbox Series X / S, the SIM update 5 for the Microsoft Flight Simulator (from 50.99 € at buy) has been published on the PC. The update includes not only exploration flights, more flight assistants and many adjustments, but also significant performance improvements. This power boost has nothing with DirectX 12 (the interface will be supported later) or to do upscaling procedures such as NVIDIA DLSS, but the developers at Asobo have reprogrammed much of the simulation and the basic engine. These optimizations should reduce CPU usage and increase the refresh rate. We checked the performance increase in three scenarios with the same preconditions (start position, weather, daytime, airplane, perspective, etc.). So the CPU utilization dropped by up to 20 percent compared to the MSF version with the SIM Update 4.
