Thanks, but no, this is not the steam version...it's not even VR, just simple 2D single player take-off, circuit, land...goes from 60fps, to <10, back to 60 fps within a second or two causing frequent stutters...

I am experiencing the same problem. Even went so far as to uninstall DCS, delete all the remaining DCS directories, reinstall with only the Hornet and Nevada...still got the same sudden frame drops / stuttering. Was running perfectly with nearly maxed out settings (I have a beefy computer) before this started...I am running Windows 11, which had a bunch of updates lately, but since you are running Windows 10, that kinda rules that out....
