Bought new 12700K CPU bit Hybrid only utilizes 20 percent of it

VsPipe seems to use up all of the RAM memory which always stands at 99 percent. I only have 8GB of DDR5 but Windows 11 uses up nearly 5 GB of it so I'm thinking it might be RAM bottleneck when Im doing 4K conversion.

Okay, 8GB of RAM was never something I would have considered, since I think even on normal Office machines using below 8 GB is just foolish.
So yes, 4k requires ~4 times the ressource 2k does, so RAM really could be the issue here.
That said, you can try whether Limiting the cache and thread count (Filtering->Vapoursynth->Misc->Script) helps, but 8GB is not much. (I'm running even low with 32GB on 2k filtering&co. Angel )

Thanks for reply.

 So I limited cache to 2000MB and thread count to 10 and now I get nearly 7-8 FPS being processed (instead of just 3 before) - so its a big gain I think.

I would also recommend to try limiting the thread count to 1 and see how it works.
But happy that is cleared up.

Ps.: SVP on 4k content uses here around 5.6-6.2GB so yes, 2GB free isn not really enough.

Hmm,... system should not get laggy, since Hybrid usualy calls everything with 'idle' priority.

Hi Selur,

I am having a similar problem on i5-12600k with low CPU usage and I figured out at least in my case it is because windows decides to run x264 on 4 efficiency cores only, not touching the remaining 12. It is definitely win10 issue, as previous comment mentioned it goes away in win11. As soon as I manually change the priority for x264.exe to normal or above normal, all 16 cores are utilized and processing speeds up several times.  So my question is: is it possible to configure hybrid to call x264 with 'normal' priority instead of 'idle' during start so I don't have to manually change priority, especially on batch processing? Thanks

Hybrid only allows to overwrite the genera niceness of all processes called.
Hybrid has an undocumented option to change the default miceness through a misc.ini file.
[General]
niceness=XXX
XXX:
-19 = idle
0 = normal
19 = above normal
49 = high
99 = realtime
be aware that this is totally untested and I would not recommend to use 'realtime'.
(only added it years ago to do some testing, but the code is still there and should work)

Thanks a lot, Selur! It works exactly as expected: at 0 all 16 threads are utilized instead of 4 E-cores only with 60-70% on each thread and overall frame rate increase of 400-500%, no scripts, just x264. at 19 CPU load goes to 80-90% with only slight increase, maybe another 5%, so I'll just use 0

Happy that helped you.
