Engine issues when changing windows
-
When I change windows, as in focusing on navigraph charts, firefox, or something else, and not having MSFS focused, the engine ITT< torque, N1, and fuel flow go down. When I tab back in to MSFS, they go back up. This is a really weird bug. For example, in cruise, my ITT was about 820, and when I switched to firefox to type this, it dropped to about 760. IDK if this is a microsoft or computer issue but I tried literally everything I could think of to fix this.

It's because the RPN update frequency is reduced when you change windows. This is the same issue as anyone building a home cockpit that struggles with frame rate drops from pop-out windows. I've heard this doesn't affect everyone, and various settings can change the behavior, so I suggest looking there. I have two monitors, and keep MSFS in fullscreen on one, while I can alt-tab, and open other windows without any change in framerate, so it is definitely a local issue, luckily, in this case.

@Black-Square Thanks so much for the detailed response! I will definitely check out fiddling with some simulator settings. Its very odd how some people have this and some people don't. I also have two monitors. It's weird because I have tried changing every setting on my computer, with no luck. I'll let you know if I find a fix.

@slipperfruit Maybe run sim in windowed mode. You can also look into windows game mode, Optimizations for Windowed Games, Hardware-Accelerated GPU Scheduling (HAGS), and Variable Refresh Rate (VRR) settings. These will all effect how a game will run when not in focus. Unfortunately I do not know of the right settings to change off the top of my head...

@SadBucket I will try experimenting with each of those seperately and will let you know when I find the fix! I am pretty sure windowed mode will fix but I hate running in windowed mode, that's my last resort.
