Sorry about the shortcomings in my phrasing – I was trying to emphasize that I wasn’t making any assumption about your technical knowledge, and instead erring on the side of over-sharing my own experiences. It’s absolutely worth asking the question, you never know when/where a solution will pop up.
And in my experience, for whatever reason, X-Plane11 (in VR) and FS2020 (in any format) with high settings will absolutely punish my system unlike any other sim/game… DCS/ATS/ETS/Assetto Corsa/iRacing/etc don’t even come close for me. I run as high of an overclock on both my cpu/gpu as I can get away with, and I pretty much do the all my OC tuning and stress-testing with FS2020 now. If it works in there, not a single one of my other titles will have an issue.
