I'll give 2. Poorly optimized shaders and you can only see a limited amount of lights at a time.
the latter is valid but i'm 90% certain that's an opengl limitation. this doesn't mean there can't be something done about it though.
with the first one you need to keep in mind that you have a possible
256k bricks to plantfind me one engine that can do what blockland does with its bricks. keep in mind these have to be non-static objects, aka not counting terrain or fixed decorative features or anything that isn't removed, added, or altered midgame.
though there is validity to the complaint, the possibility for improvement regardless of what engine we're working with is slim
vehicle physics is a big one
yes, i agree
This engine is very old, code needs to be replaced/facelift.
again i would direct you to the constant facelifting that has been occurring and the work involved in replacing this engine
