Steam VR constant cpu late start

[Khaleesinikov]

as title says, i get constant cpu late starts in every single game i play causing dropped frames.

Even when the performance graph is fully green, the cpu late start is still there constantly, and after a bit of time it will cause dropped frames. For example in vtol vr i can fly around for a minute with a butter smooth experience and then suddenly start dropping frames or whatever the red line in the performance graph means. This includes every game i play.
 

I did set vr pre rendered frames in nvcp to 4 and that helped a bit, but i then set it to app controlled and it helped more meaning that the games werent constantly in their choppy state.

cpu and gpu usage never reach 100%, usually my gpu hangs around 60-70% and my cpu around 50-40%.

Specs:
Ryzen 5 3600
GTX 1660 super
Dev edition HP WMR headset
16Gb ram
Win 11

SS is at the recommended 150% global and 100% app. Changing it doesnt help anything.
Here is the Frame Timing graph at 20% Global SS: https://ibb.co/TwL34Dd

Everything is updated to the latest version. I had this issue for a long time but i just got used to playing like that and now that i have felt how its like to be buttery smooth i just can't go back.

Thanks in advance
