(Fixed)Smart smoothing does not work properly since yesterday

I wonder no one report this issue. or is it only me?

Smart Smoothing doesn’t work properly since yesterday.
The only change since then was Steam VR update. smart smoothing give a terrible image.

Running oculus games from pitool is fine. but only Open VR games. I’m using 245. I have to use this version for stormland. I just want to know my case is rare or common now because no one reports it.


I fixed myself. change refresh rate 80 to 64 and turn back to 80 makes it fix.
