Need help whit encoding (Interframe parameters)

[Selur]

Changed to VVEenc and now I get from 22fps fast the triple 65fps now I'm using my cpu on 55% and only 33-35% of my gpu.

I assume you mean "NVEnc".

I wonder is there something to increase they performance? A better preset ot a ultra performance preset?

no really:
a. Not using Avisynth, but Vapoursynth (or at least 64bit Avisynth) might speed things up a bit, since it seems like the filtering is the main slow down.
b. in case the source format of your input allows is, enabling hardware decoding might help (probably not much since my guess the filtering and not the decoding slows things down.
Other than that, frame interpolation isn't that fast to begin with Interframe is one of the fastest methods since it's gpu assisted.
In general make sure to:
a. have temp and source path on different drives (this will mainly speed up extraction and muxing) (ideally all on ssds)
b. make sure your source, temp and output folder are not monitored by anti virus software and similar since they slow down the access to files. (This is mostly a slow down when handling image sequences as sources, but depending on the system might slow down things.)
-> I doubt much will change, but small speed increases might be possible.
