Yeah, it does chug there a bit unfortunately. Keep in mind the minimum requirement is a Ryzen 3 or equivalent, so if your system is worse than that I probably won't be directly targeting it for optimization. On a Ryzen 3 with decent memory it runs fairly smoothly most of the time in that area, but I'll admit it's still less than ideal. There's no good way to optimize it unfortunately without cutting up the map, which I may do eventually but will be...quite the project to migrate all the scripts correctly. In the meantime though no, unfortunately there's not much you can do on your end.
