TUTORIAL: Show Other Applications and Whole Desktops in VR

I have RTX3070 and Reverb G2.
I tried to bring the desktop from the Cliff House to MFS2020 VR using the method from the video but I have huge performance drop from 32 FPS to around 26 fps.
I wonder what is different between our setups, that you don’t suffer performance drop.
My settings:

  • render scale in the sim 70% TAA
  • OpenXR 100%

Maybe I’m running out of VRAM?

I’m getting smaller impact of having the desktop in the cockpit when I bring my setting down to:

  • render scale in the sim 60% TAA (lowered from my default 70%)
  • OpenXR 100%
