Entity Culling

Vanilla draws every tile entity in the player's view, including ones fully hidden behind terrain, so a base or dungeon with hundreds of them can cost a lot of frames. Entity Culling is a client-side optimization that skips rendering those hidden tile entities. Two culling methods are available: the default uses OpenGL occlusion queries, which give pixel-accurate bounding box culling with about one frame of delay and a small overhead. The second uses a raytraced check on the CPU. OpenGL 4.3 hardware is needed for the occlusion method, and the raytraced method is more CPU-bound while the OpenGL method leans on the GPU, so the better choice depends on the machine.

The mod is published for Forge only, with files for 1.12.2 and 1.16.5, and its latest file, 1.16.5-2.1.7, dates from 2025-08-27. It needs MixinBootstrap and RenderLib, and it works with the Mixin 0.7-0.8 Compatibility mod. The author reports a large gain in a test inside a Chocolate Quest Repoured dungeon with about 200 entities on screen, where most were occluded. Only the client needs it, so servers do not change. The code is not open source; the author retains all rights, although public links for the source code and issue tracker exist.
