Observed behaviour
The screen share frame rate is extremely low. When looking at the GPU in task manager under performance, you can see a direct correlation between the GPU compute utilisation going up and the encode utilisation going down (Data visible only on Nvidia GPUs).
Reproduction steps
- Go to Windows settings in System > Display > Graphics.
- Under "Advanced graphics settings" enable Hardware-accelerated GPU scheduling.
- Play a game that uses high GPU utilisation. Use monitoring tool to ensure it is pinning GPU utilisation 98% or above.
- Start a screen share for the game on the host device.
- View the screen share on a secondary device.

Expected behaviour
The screen share should be smooth, matching the expected frame rate of the stream.
