Minecraft Forums

Hi everyone. I've been having issues with Minecraft lately. The game seems to enjoy crashing a lot on me, mostly while playing minigames on servers. I know it's not anything to do with playing for long periods of time, as It happens sometimes mere minutes after launching the game. I have 1.9.2 Forge with Optifine and WorldEdit. Another common occurrence is where the game freezes, but still let's me walk around, chat, break/place blocks, pause/unpause, etc. It's just a frozen image on my screen, and I have to use Task Manager to close it. The crash report from the actual crashes, not the freezes is this:

I'm not sure if this is something on my part or with my computer or something with Optifine or WorldEdit

Thanks!

Try without mods.

Well you see, that's the issue. I either play without my precious Optifine and run 20-30 FPS or use Optifine and get a tasty 45-60 FPS but run the risk of crashing halfway through a game of SkyWars :/

Try turning off Fast Rendering

nah I always leave that off

Also, sometimes I have to log in again when opening the launcher. Maybe I'll try backing up my worlds and re-installing it entirely

You don't need forge in order to use optifine, just double click the optifine jar and your good to go.

Wow thanks dude I got rid of Forge and now just use Optifine and it hasn't crashed since. I never used WorldEdit anyways

No problem. Just happy to help.
