"Uhuh, noodles, just allocate more ra-" atatata. no.
I have tried this. I have 16 gb of ddr4, and have allocated every number i could possibly think of in the allocation area and NOTHING WORKS.
The crashes/issues differ. It always loads fine the the main menu, but as soon as I join a single player world/server/realm I either get one of three things as a little middle finger in my screen;
1: "Minecraft java has run out of memory!" The classic error screen, with the dirt filled background and grey text. not a crash, but implication that it did.
2: "java.lang.OutOfMemoryError: Java heap space" Crash. Gives me a crash log 50% of the time. Its really odd.
3: Straight up crash, with the "sorry for the inconvenience" text. No crash log.
This is EXTREMELY infuriating. I have re-installed java, 32x to 64x, old versions to new, re-installed minecraft, tried other flipping launhcers (Technic, ATlauncher, Twitch, Badlion, etc) AND THEY ALL DONT WORK.
