Frequently asked questions

How do I turn on Optifine Old Lighting Shaders?
Open Options, then Video Settings, then Shaders, and pick Optifine Old Lighting Shaders from the list. If it isn't listed, click the Shaders Folder button, make sure the pack is inside that folder, then reopen the menu.
What does this shader actually change?
It recreates the classic lighting look from OptiFine's old internal shader options, bringing back the familiar light shades of older setups. Textures, blocks and the overall vanilla art style stay the same.
Will this shader lag my potato PC or old laptop?
It's built to run smoothly on low-end PCs and laptops and to keep frame rates stable during normal play and around big builds. If you still get stutters, lower other OptiFine video settings such as render distance.
Does it make Minecraft look realistic like other shader packs?
No. It aims for simple retro visuals that keep the vanilla feel, not realistic or heavy effects. If you want dramatic reflections or volumetric lighting, this isn't that kind of pack.
