Which OptiFine edition should I get?OptiFine Ultra is the most popular edition.
Do I have to configure OptiFine to get better FPS?Usually no. OptiFine comes with many optimizations that should increase the FPS without any configuration. You can further increase the FPS by configuring the Video Settings and finding the trade-off between quality and performance that works best for you.
How can I configure OptiFine for best FPS?Go to the Video Settings menu and look at the tooltip shown for every setting. It should show which value to set for better FPS and which for better quality.
Why are some world chunks flickering with OptiFine?Most probably you have enabled "Chunk Loading: Multi-Core", but the graphics card driver does not support it properly. To fix it go to the graphics card control panel and set "Threaded Optimization" or "OpenGL Threading" to OFF (example). For best results disable it globally, not only for java.exe or minecraft.exe.
Why am I getting the same or less FPS with OptiFine installed?OptiFine generally increases the FPS (200%+ is common) and in the worst case it should be the same as vanilla Minecraft. There are many reasons why in some cases the FPS with OptiFine may be the same or lower than vanilla:
Even if the average FPS reported in the debug screen is the same as vanilla, the gameplay with OptiFine should feel smoother and more fluid. There are several OptiFine options (Chunk Loading, Smooth FPS, Smooth World, etc) that can further reduce the lag spikes and stabilize the framerate.
Can I include OptiFine in my modpack?Generally no, unless you have an explicit permission from us.

I gave the wrong username when donating, what can I do?If the username capitalization is not correct (upper/lowercase wrong), then login on the cape change page and the capitalization should be automatically fixed.

My cape was active, but it is now missing. How can I recover it?You can recover the cape on the donator login page where you can assign a new username for the cape.
