Hi all, I'm also having trouble with unresponsive/laggy updates on the display of the SD+.
What I've noticed is that when the MSFS window is focused, the display becomes much more unresponsive. When MSFS is focused the SteamDeck.exe CPU usage also increases quite a lot. However, when I focus a different window (e.g. by alt tabbing), the performance of the display is good and SteamDeck.exe CPU drops dramatically. What's odd is that even when MSFS is not focused there does not appear to be a significant performance drop in the simulator.
This might be related to the issues with laggy displays in the Fenix A320?
Any ideas to why this might be the case or how I might go about fixing this? Thanks!
