You should be able to get faster than realtime on that CPU . 8C/16T . Try Prefetch(16)

Don't go faster than preset="super fast" for QTGMC, otherwise yadif or bob is used for the repair mode . In that case you might as use yadif(1,1), or bwdif(field=3) .

@poisondeathray, Thanks, Prefetch(16) increased the speed by about 20%.
I will try yadif(1,1) and bwdif(field=3)

If you are not gonna supply sample, what is rez [EDIT: and colordepth] of your source ?

Maybe other could give better args to QTGMC for HD source. [blocksize, subpel, and others, I usually just use a preset, if I use QTGMC at all]

EDIT:

your CPU has 8 cores, 16 threads with hyperthreading,
suggest at least try Prefetch(8), and maybe 12. [it varies but physical cores often recommended]
