Bevy 0.6 was published a week ago, and it have better performance than 0.5. In the offical example many_cubes, it can get near 60 times fps.
I do plan to keep my Code simple so it will be easy to update to newest Versions whenever they come out. Nobody would want to be stuck with antiquated Engines for too long.
Or be constantly updating to master so it’s hard to get out of sync, lol.
