There are many reasons why in some cases the FPS with OptiFine may be the same or lower than vanilla: OptiFine generally increases the FPS (200%+ is common) and in the worst case it should be the same as vanilla Minecraft. Why am I getting the same or less FPS with OptiFine installed? To fix it go to the graphics card control panel and set "Threaded Optimization" or "OpenGL Threading" to OFF ( example).įor best results disable it globally, not only for java.exe or minecraft.exe. Most probably you have enabled "Chunk Loading: Multi-Core", but the graphics card driver does not support it properly. Why are some world chunks flickering with OptiFine? It should show which value to set for better FPS and which for better quality. Go to the Video Settings menu and look at the tooltip shown for every setting.

How can I configure OptiFine for best FPS? 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. OptiFine comes with many optimizations that should increase the FPS without any configuration.
