They can almost certainly fix that with a combination of a lower rendering distance (less stuff to load in the first place) combined with lower quality assets in split screen (every individual asset uses less memory). Again. This stuff is basic. Really you’re supposed to build for your minimum spec first and scale up from there. I guess they were more concerned with bear sex than getting their game to run on all platforms.
I, too, enjoy being locked into a single Canonical run repo.
