Hybrid works only on 50% performance.

You can disable MT which should be faster than using mode 5 or higher.
+ I agree MT is probably not the issue. Partially because this also happens with Vapoursynth where no MT is used.

Also i think it is not actually SVP issue but InterFrame/Avisynth issue.
I mean i can just turn on player get 4k movie in it and SVP will convert it to 60 fps on fly and it uses around 100% of my cpu (which is understandable for 4k res).

So clearly there is something between SVP <----------> Interframe/Avisynth

Imo SVP is not an issue so it should be either Interframe or Avisynth.
