Depends. How's your framerate?

Optifine is a mod that adds extra graphical options to further make your game look however you want, and frequently boosts your average FPS by around 20. :D

And also, my game would drop to 0 fps after entering Middle-earth, and then it would crash... Optifine keeps my fps high enough to prevent freezing. IDK if optifine will work for you if your framerate is good.
