Today I was working on new terrain system and optimatization. On te image is world with render distance 128 - unfortunettly its not fully loaded beacuse it takes ages to load 66k chunks. Game preallocates required memory. This world requires ONLY 1.5GB VRAM and 1.2GB RAM. Vanilla minecraft runs 120FPS with render distance 16 on my laptop while my game runs 30FPS with render distance 128 which is 65992 chunks more. minecraft basiccly render 1.6% of what my engine can do.

Keep in mind that i have rtx 3050 4GB laptop
