What I’m noticing, is yes, if MSFS is out of focus frame generation “turns off” - however if I click on my right or left screen the center monitors returns to frame generation being on but the left and right still do not follow.
This appears to be a pipeline rendering issue with the sim itself more so than an nvidia issue - though it might need to have both parties involved to solve the issue entirely. If they are going to support view ports from the main view like other sims - they should find a way to support this option across all view ports…at least I hope.
