VanillaFix - Minecraft Optimization and Stability

VanillaFix is a modification that significantly improves performance and fixes various errors in the standard version of Minecraft. Many users report FPS increases of up to three times - you can verify this yourself! Additionally, with VanillaFix installed, the game no longer crashes completely. Instead, you're returned to the main menu where you have the option to upload an error report to a specialized service for easy sharing with developers (you can test this feature by pressing F3 + C in the game).
