Camera Raw (13.1) is extremely slow on Windows 10 PC

Hello!
I am having issues with camera raw when editing RAW photos. 
It is so slow I cannot work with it at all. Last time I checked (around v12.0) , I had this problem and had to do my work on another pc, then haven't used it for some time. How is this still an issue several versions later? I am very annoyed. I tried all the steps mentioned in troubleshooting. Thank you for your help, and I trust you finally fix this issue so I can use my products that I pay money for. 
Best regards, Robert
