CPU overloaded when generating stems in live mix - Sound Problem

Hi, I am a really big fan of the new stem feature of traktor 4.
Unfortunately I cannot use it during mixing. When I play a track while I am generating stems on another track the sound is robotic and stucks and slows down until the process is finished.

No I don't need any helpful tips how here to optimize my Windows or energy management.
I have a Ryzen 9 6900HX, nvme SSD, 16GB RAM so this should be fine.
In parallel I also use DJUICED which supports live stem generating and here I have no problem at all.
Is this a known problem which is in work or do I miss anything here in the Audio Setup?
I tried all buffer sizes on USB and ASIO. I also tried WASAPI and internal Soundcard.
If I can make a proposal here, try to cap the CPU usage for stem generation here to ~60%.
This will be enough buffer to make live mixing and stem generation possible. Will take some seconds more but it does not kill the complete mix.
Thanks and I hope someone can help me.

Best regards

    Yeah, it's a known thing. Currently the stem separation is CPU only, unlike most other DJ software which can use the GPU.

    In Traktor it's more of a prep tool and not so much for live mixing.

    Ok thanks for your fast reply here. When GPU is integrated in the CPU you have the same problem here. The final result of the stems are a bit better than in DJUICED but the performance is worse. Maybe Traktor find a way soon to implement it in live, same like DJUICED.

    Integrated GPU or not has nothing to do with it.

    Not with the problem but you say others use the gpu instead of the cpu. That's why I mentioned that in an integrated system it will lead also to high consumption. A performance cap is needed with gpu or not.
