Slow pc ? rendering time ?

Hi,

i am most of the time an audio guy using audition and recently started using after effects.

I bought a new pc : Win 10 pro, Ryzen 7 Processor, 32Gb ram, GeForce GTX1080Ti, several ssd's

Started working on it and it's really fast, reliable and stable in audition, but when i have a project in after effects, it's slow, very slow, for instance, i have a project ready, i render it on my 6 year old i5 processor laptop with 12Gb ram and no special graphics card and it takes 34 minutes to render, if i render the same project on my new pc it takes more then 4 hours !  Tried contacting the adobe helpdesk, but did not receive any more help, they said, it probably is a hardware issue and they are a software company so, go figure it out yourself...  so now what ?

Someone knows why that is happening ? I've also noticed that Ram preview is almost non existing on my new pc, it just wont work...

When i opened up task manager, i've noticed that my processor is only at 11% during rendering ?

    Here is a drastic experiment go into your BIOS and disable half your cores and see how your system performs according to testing by

    Puget the more cores you throw at AE the slower it goes

    A little reading on the AE forum, this is known problem and Adobe is looking into it for several years now

    I am guessing that you have not tuned your computer to get rid of excess processes that are stealing memory and more importantly CPU time. Do you have Premiere Pro installed?  I ask because I have the Premiere Pro BenchMark (PPBM) that can test your hardware using Premiere Pro.  On that site you can see some other Ryzen results.  Submit the results to me and I will comment on them.  I have seen great results from some Ryzen's.

    yep i have the whole suite, but it's been 15 years since i last edited in premiere... i will download it and see what i can do and send you the results.

    What bothers me is that there is no load on he cpu, when i am rendering it only works 11% ?
