OptiFine 1.13.1

OptiFine 1.13.1 HD ULTRA is one of the newest preview versions of OptiFine 1.13.1 before it has been released live. This mod has already fixed some of the common issues from the previous preview versions such as shaders fix and Java 9+ crashes.

With OptiFine 1.14 still coming, we are gifted to try and preview using this version of the mod. This version has already patched up plenty of obvious bugs and glitches. This includes the fact that they have already fixed and removed the check for lowercase resource locations. This version has also added Fullscreen Resolution. So far, we are only a few ticks away before OptiFine officially releases the 1.14 version. But for now, let us enjoy these lower versions for the meantime.
