well, 5400x2700x60 is indeed equal to 4x4Kx30, which is a lot of pixels 
but it shouldn't be a problem for NVOF, there's a bottleneck somewhere, I'll try to take a look
"35% charge, but 2 threads seems to be overcharged at 100%" - with NVOF, right?
still making 80 fps out of 60 is not the best idea, I doubt it can be fluent anyway
just watch 60 fps in 60 fps, it's already good enough 
30 -> 80 or 60 -> 120 make sense, but not 60->80
even IF can be fluent, EVERY output frame will be interpolated, i.e. with a visual artifacts
and don't forget that in Whirligig/SimpleVR/etc we are limited with an outdated and software-only ffdshow video decoder
> i thought 60fps to 80fps will be easier than 30 to 60
nope, it's at least twice as hard (w/o NVOF)
