Hey @SpecteRED I believe I'm having the sime type of issue. I have a 9088x3D on a MSI Tomahawk x870e motherboard. (I'm still running my old trusted 3080ti, and only play in 1440p trackIR). Ironically, in June's update it went away and performance was solid, but that only lasted to aug or july, I'm not sure. I can lower the settings, I can do everything, but I still get those slowdowns and frame time spikes. Using Task manager I am now very confident every time I got a spike, I have a small read spike in my DCS installation SSD. And empirically, it seems to get much worse on heavier terrains, such as afghanistan (although, now, with the uprezzed textures, Caucasus is also giving me a lot more problems). So I am suspecting something is wrong on the terrain loading/cache. I believe ED was working on a new terrain engine, so it begs the question... Still, this is a pain and has been keeping me from enjoying DCS for some time now. Can you check to see if the spikes come with an SSD read surge as well?
