It begs the question: What background processes does MSFS use?
The answer for me with my current settings is: I don’t care.
I started at 95% in the menu and the same while flying before I did all my testing and tweaking yesterday and today. My GPU Load is down to 10% in the menu screen, and significantly lower while flying at 80 FPS (down to 69% - a significant improvement.) That’s fine by me.
Hopefully my previous posts can help someone achieve the same goals.
