How would I go about doing that?
I think they mean they have to optimise the game engine. If that's the case, it might not be their first priority unless patrons are finding it to be a common problem. Unfortunately that kind of work is a serious pain in the butt and can't just be done in a weekend. Oh well. I'm not a patron myself so I can't really complain. Best thing for non-patrons to do is be patient and keep your fingers crossed.
