Optimized Fullbright Mod changes how the game handles light to give you perfect vision in the dark. It completely disables the lighting engine instead of just turning up the brightness. This stops the game from doing math for shadows and light levels, which gives you higher frames per second while you run through caves or build massive farms.

Features:
- True Fullbright: Gives you clear vision in dark caves and at night without needing torches or potions.
- Better FPS: Stops the game from calculating light updates to make everything run faster.
- Shows every block at light level 15 on your F3 screen so you know the mod works.
- Helps reduce lag near large redstone machines or piston farms that usually cause heavy light updates.
- Only changes what you see on your screen and does not alter any actual game rules.
- Plays nicely with other speed mods like Sodium and Bad Optimizations.
How to Use:
- Press the G key on your keyboard to turn the bright vision on or off.
- Open your game controls menu to change this button to a different key if you want.
- Open your F3 debug screen to check if light levels say 15 when the mod is active.
