Illustrator suddenly switching to CPU preview, GPU preview greyed out
I have a document with some large images that suddenly switches my view to CPU Preview shortly after opening, or sometimes when zooming. It'll freeze for a moment before switching to CPU, and GPU Preview will be greyed out. I was able to fix this temporarily by switching to Outline, saving, then closing and reopening the file, but it keeps happening regardless. Does anyone know what's causing this, or how to fix it?
