Theres EXTREME lag issues to start. I have a great computer so its not that its horrible. Yesterday i was playing the game at Fancy, smoothest lighting, chunks at 8 at 120+ fps and today i dont get 25 on a superflat at the fast, least amount of lighting, and chunks at 2.
Why doesnt mojang instead of making commands for command blocks or changing the rendering, actually use its own engine. Like seriously its using Java. Java is horrible for games. Theres random content that is pointless such as banners and more commands, but minecraft still not having its own engine. What would you rather have? An actual GOOD game, or a game with random content for no reason.
