You might like to consider the following tweak. It made a huge difference to clarity and smoothness for my CV1.
In my case, I chose to use in-sim res of 80% and Pixel override of 1.5.
In short, you reduce the in-game resolution and have the oculus driver boost it back. You also set a framerate of 30 and allow the drivers to boost it back to 60 via Oculus’s ASW feature.
