Stutttering and poor performance in Photoshop V25 (and V26)

Hello, thank you for giving your interest.
My V25(long term support) photoshop seem to not working properly causing lag and stutter performance while other softwares do not, especially when I use brush or rotate tool, photoshop's task manager process will immediately consume up to 100% both CPU and GPU.
- I have 5 displays connected but I only use 1 for photosho pand another 1 for reference, other remainings were put to sleep.
- Changing memory usage down to 80-70% does not help
- Both of V25 and 26 currently have the same issue

What I do not understand is why does its performance so poor? Is it reasonable or I'm

I'm using RTX 3070 with i9-10900k on 2560*1440 resolution screen. The additional informations were attached below.
Thank you.

    First of all, never, ever, set Photoshop memory allocation to 100%. That will choke your whole system and grind everything to a complete halt. Set it to 60 or 70% max. Other processes need memory too, even plugins like ACR need their own memory.

     

    Photoshop will take all that memory very quickly and hold on to it. Photoshop memory is reused and recycled, not released until you quit the application. Thi is by design and what makes e.g. batch processing possible.

     

    Photoshop's main memory is the scratch disk, RAM is just a cache for the most current data. Make sure you have enough free space, 200-500GB depending on file sizes and how many you have open.

     

    Second, you have an Intel UHD integrated GPU somewhere in the mix, and most likely it conflicts with the RTX. In system info, all your displays are listed as active and connected to the Intel UHD.

     

    Photoshop uses the GPU for actual data processing, and the result returned to Photoshop for further processing. You cannot send data to one GPU and get it back from the other. There can only be one GPU in this equation.

     

    The standard advice for an integrated GPU, if it causes conflicts and problems, is to disconnect it completely in the OS or driver:
