Is VapourSynth R57 broken somehow? At first I blamed Windows 11's new termimal for the very slow throughput (slow pipe transfer?), but nope, even using ffmepeg with -vapoursynth, the process is extremely slow, using CPU for only like 25%. Both QTGMC and MCTemporalDenoise seem to grind to a near halt. All on my new i9 12900K. This used to go blistering fast, even on my old 6700K.
Here's what I do (see below). It's almost as if multi-threading is broken for these two functions (it isn't, but appears to work exceedngly inefficient). This is 4K material, btw.
E-cores are hardly used (some are marked as 'parked' even). But even the P-cores hardly see any action. See:Code:import vapoursynth as vs import havsfunc as haf core = vs.core core.max_cache_size = 65535 vid = core.dgdecodenv.DGSource (r'c:\jobs\am.dgi', ct=44, cb=44, cl=0, cr=0) vid = haf.QTGMC (vid, InputType=1, Preset="Very Slow", TR2=3, EdiQual=2, EZDenoise=0.5, NoisePreset="Slower", TFF=True, Denoiser="KNLMeansCL") vid = haf.MCTemporalDenoise (vid, settings="very low", stabilize=True) vid = core.neo_f3kdb.Deband (vid, preset="veryhigh", dither_algo=2) vid = core.std.AddBorders (clip=vid, left=0, right=0, top=44, bottom=44) vid.set_output ()
CPU saturation
N.B. I had the same issue on my previous i7 11700K, btw.
P.S. Does it matter my plugins folder has 148 plugins in it? (all 64-bit recent vapoursynth plugins someone posted here).

Assuming you:
a. made sure to disable any anti virus etc. (or at least added execptions for file input folder etc.) to be sure that it's nothing like that
b. your system isn't thermal throtterling
benchmarking the script with vspipe and '--filter-time' should help to see which filter slows down the script the most,...
Code:"path to VSPipe" --filter-time "path to script" NUL

Okay, then look at what happens if you don't use just QTGMC and then add the additional filters one at a time and later ony by one and also look at the speeds of the encoding.
This should help to understand where bottelnecks are located, also check the speed without deinterlacing, may be QTGMC already slows down your processing so that any further processing doesn't really matter in regard to speed and cpu usage.

Well, the matter is resolved. Looks like it was the E-cores, after all. I found a very useful option in the BIOS to disable the E-cores, pressing ScrollLock while in Windows 11 (it doesn't actually disable them, just marks them all as 'parked'). Now I get a blistering fast, sustained 100% CPU saturation again on all P-cores.
Even though heretofore the E-cores appeared to be hardly used at all, nonetheless they were the source of the (significant) hold-up
