Unfortunately, 60FPS in msfs are hard to reach when flying airliners to big airports like KORD with vatsim traffic and a huge photogrammetry areaaround. So, it will lag and stutter tremendously if you are not constantly over 60fps. 30fps is reacheaböe woth a headroom and increases the immersion drastically, compared to a laggy stutterfest as soon as FPS drop below monitor refreshrate.
So, i have the choice to spend 3000$ on an 7950x3d and a RTX 4090 to have moreframes in a computer game, or spend that money elsewhere, like IRL flying. I know what i will choose…
