i created a modpack for 1.12.2 with about 60 mods and im using the same forge 1.12.2 and optifine.
I only have this problem that every time I start the game with optifine in the loading stage "Loading Initializing Minecraft Engine (3/7)" "Rendering Setup - Loading Model Manager (3/5) 1/1) "the game simply freezes and continues the loading process extremely slowly, taking 40 minutes to finish and return the normal loading process and if I interact with anything else or click on the game it stops responding and does not load anymore.
I have tried reinstalling forge, reinstalling java, reinstalling minecraft itself and nothing has seemed to fix this issue.
my pc specs are:
Intel Core i5-4210U
Intel HD Graphics 4400
12GB DDR3 Memory
HDD 256GB
Please help as i want to play with this modpack
