is there really nothing I can do to get rid of microstuttering?
Did u try to enable Statistics in Nvidia App and check if you are giving extra breathing room for your GPU?
For example if it mentions your assigned fps target but it shows something like 98% GPU usage and the FPS value keeps dropping under it like this:

then u should resize it down a bit until your GPU usage % goes down and your FPS value is more stable like this:

That should lower significantly the instances when micro stutters happen cause of low resources.
Ooh by the way if u accidentally use the vsmlrt.py from 9.2 archive it will fail to find the rife_v2 folder models.
Attaching below the out of the box SVP vsmlrt.py file cause it still works with 9.2 and can also find the rife_v2 folder models.
