Frequently asked questions

How do I turn on Cosinus Shaders?
You need a shader loader such as Iris or OptiFine. Open Video Settings, go to the Shader Packs (Iris) or Shaders (OptiFine) menu, select Cosinus, then click Apply or Done. The wavy effect should show up as soon as you return to your world.
Why is my whole screen wobbling and warping?
That is the pack working as intended. Cosinus applies screen effects based on cosine math functions, which bend the view into wavy, cursed-looking scenes. It is a stylized novelty pack, not a bug or a broken install.
Cosinus doesn't show up in my shader list, what did I do wrong?
Make sure the pack is inside your game's shaderpacks folder and that it isn't buried inside an extra folder. Also check that Iris or OptiFine is actually loaded, because the vanilla game has no shader menu. Reopen the shader menu afterward so the list refreshes.
Will Cosinus Shaders lag my low-end PC?
It is built to be lightweight and run smoothly on low-end computers without causing frame drops. If you still get stutters, lower your render distance and other heavy video settings, since those usually cost more than the pack itself.
