How to Reduce Lag and Improve Performance with Athena

Why Athena Helps Performance

Athena bakes a separate model per block type and only runs its connected-texture logic where it is needed, instead of recalculating connections for every block every frame. That design means most of your performance tuning is about not fighting it — giving it clean, compatible assets and avoiding redundant model loaders.

Trim Conflicting Mods

Running two model or connected-texture loaders at once forces extra work and can cause both to fall back to slower paths. If you have another CTM or model-loading mod installed alongside Athena, test with just one active. Fewer overlapping systems generally means smoother chunk loading and fewer stutters when new areas render.

Keep Packs Lean

Large resource packs with heavy CTM definitions cost more to bake. If you notice hitching when entering new chunks, try a lighter pack or disable packs you are not actively using. Because Athena caches baked models, the first load of a chunk is the expensive part; once baked, rendering is cheap. Letting chunks bake undisturbed — rather than rapidly toggling packs — avoids repeated re-baking.

Watch Special Cases

Athena's custom checks, such as vertical culling for glass panes, exist to skip hidden faces. If panes or similar blocks still render their concealed sides, a pack is overriding that behaviour and doing extra work. Using a pack that respects Athena's culling keeps those savings intact.
