Rendering complicated files on MAC requires CPU rather than GPU
Something is wrong with GPU rendering.
My old iMac (27" 2016) used to have rendering issues with larger/complicated files. For example, using the HAND tool and moving around, sections would not render/refresh.
I thought, well it's an old machine the GPU must be dying.
Then i got a new MacBook M1 MAX with 64GB Memory.
And I still often see rendering issues and need to switch to CPU.
