That’s a good guide. It’s worth pointing out if you deviate too much in cpu/gpu specs and resolutions you could be in for a hard time. Of course there are ways to mitigate some of this but for that you need an intimate understanding of how the sim works.
With dlss as a compromise my 5800X, rtx3060 system can run 4k ultra @ 30-40fps without problems. And at LOD 400 however using 3rd party airliners and apps would likely need a reduction.
