Super OLED + Pimax Play2,0 = No Smart smoothing

Hi.

Smart smoothing disappeared when I switched to version 2.0.
I have tested both old and new Nvidia drivers. v581.80 v595.97 and more in between, without any difference.
OpenXR runtime is of course selected.

Then I uninstalled Pimax Play2.0 & installed v1.43.9. Smart smoothing was back.

Then I tried installing 2.0 again (clean installation) then Smart smoothing disappeared again.

Please help me understand why.
By the way RTX4090

I have Pimax Play 2.0 installed, and the Smart Smoothing feature is available on my system.

Would you mind exporting a log file and sharing it with me? Please make sure you have 2.0 installed and select the “Clean installation” option.
