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..
