To Use Optifine

Once you’ve finished installing Optifine, launch Minecraft. On the bottom-left in the Minecraft window, select Optifine from the drop-down menu, or create a new profile for Optifine. You can use different versions of Optifine by creating a new profile for each version you want to try. After you select the profile, simply start Minecraft the way you normally would.

When your world loads, you should notice some significant changes in how everything looks. In the Options menu, go to “Settings” and select “Video Settings.” In the video settings, you will see many options that weren’t there before. Take your time and get familiar with all the new settings and then play around with them to make the best of the mod. Press F3 on your keyboard at any point to bring up the version heads up display and see which version of Optifine you’re using.

If you’re not seeing Optifine in your profile menu, you may have installed it in the wrong directory, or your runtime environment isn’t correctly updated.
