Let’s put it like this: in most normal games, calculating the graphics is the most demanding task, so that’s where the GPU is limiting the rate of frame rendering. In sims like MSFS on the other hand, there’s also a terrible lot of physics and other stuff to calculate, which is done on the CPU. If the CPU can’t keep up with that, you’ll see a main thread limitation and a great GPU isn’t getting you any better performance. Now with MSFS the case is a bit more delicate because the coding appears to be sub-optimal, in such that even powerful CPUs are not properly used to their full capabilities.
