I have read somewhere that for whatever reason, MSFS does not respond well to overclocking, however - and I say this as a BIG however - I have a Ryzen 9 3500K 12 core and I can get it all the way up to 4.6ghz - that's really not bad - but I use Ryzen Master - not the BIOS to overclock, so maybe that helps. I don't really think MSFS should be a game that really needs overclocking to begin with either, as I've had nothing but nice smooth experiences with it. :)
