【Camera Raw is Super laggy on AMD CPU】https://community.adobe.com/t5/camera-raw/camera-raw-is-super-laggy-on-amd-cpu/m-p/10753299#M284774
Why the portable PS is fast because there are no lens profiles. I went to C:\ProgramData\Adobe\CameraRaw and renamed the folder. I opened the PS and it was ready fast. I changed the name back and I deleted all the other brands I don't need. The camera raw was slow again. So, is something in here but not the profiles.
I started my test again. I rename the C:\ProgramData\Adobe\CameraRaw\LensProfiles\Index.dat The camera raw was fast again.
In the end, I can tell Index.dat makes the camera raw very slow on my computer. It's been a year. Can you fix it?
The videos with or without lens profiles test:
Have something to add?
