I would be curious on that answer as well. I have noticed it also. I have 64Gigs of DDR5 and a 10GB RTX3080 card and i struggle to work on the app with constant random crashes and shows me same red error messages. Video memory being almost full, and not using anything out of shared memory, while this is what it is for. Yes performance would drop in viewport as of course is much slower, but who cares, if i can continue working without crashes. If i forgot to save, not even autosave can help much, and i have to do many things twice.
