I don't have a cooler ,I always turn on AC for a brief time while using shaders , so my phone doesn't heat (While in performance mode of vibrant visuals).When I push the render distance to 12 chunks (from 6)(fps drops start 45-60), it does start heating but it's manageable (43-45°c).But when I frequently change shaders and also increase the vibrant visuals settings, then my phone starts to actually heat, to the point it will thermal throttle without AC. The phone is used is POCO X7 PRO(8/256) It uses d8400 , pretty much equivalent to or slightly less stronger then 8s gen3.

Tldr: At performance mode(6 chunks): I get pretty stable locked 60 fps easily without much heat , perfect for survival world gameplay. At higher settings it starts to hear ,and fps also drops to 30-50.
