problem with enabling graphics processor usage on Imac m4

[korzenienaglowie]

 Hi! I have had an imac m3 16gb ram for 1 and a half years and editing on it is fantastic, truly amazing!

I have had an new imac m4 in my studio for a few weeks (with better ram - 24gb, and better processor version)  and today I noticed something that tires my eyes and slows down my work. This effect is blurring the photo for a moment after zooming or using any slider or editing option from the program. I started searching the web and read about suggestions with creating previews for optimization and direct catalog optimization itself. Unfortunately, it does not help. I noticed that on my imac m3 I have the use of the graphics processor turned on, (on automatically) and probably thanks to this I owe the comfort of work for the eyes and fluidity at my home. Unfortunately, according to the information that Lightroom gives me in the settings I cannot turn it on on the imac m4 in my studio because it is not supported, the option is not available, not clickable, grayed out. I have the current version of Lightroom. What should I do? I will go crazy..

1. Try deleting the Camera Raw GPU Config.txt file, following steps 2 - 5 of this article:

2. Delete any TempDisableGPU2 or TempDisableGPU3 files. Read the instrructions carefully about the Lightroom Classic subfolder:

3. If these steps don't help, do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.
