Just joined up to put my two pence in. It's a wonderful app [thank you] but here's the thing...
When I'm having issues with stuttering and I start the app, for a brief few moments the stutters completely vanish (with no apparent degradation of graphics quality either) - only to return again a few moments later. What's happening in those few moments as the app 'hooks in' to MSFS and effectively stops the stuttering? Could that be worked on and expanded perhaps? It does the job but the smoothness doesn't last!
While I'm here, I read that the app needs to be started before MSFS - is there a specific reason for that? 😎
