So first off, how much ram should I be allocating to 134 mods? I've read multiple articles that have varying answers. Second, what is usually the cause of a world not loading and going back to the title screen. If I allocate less than 4 Gigabytes of ram to the game, it hits the memory ceiling and the game is unplayable. (Assuming I get a world to actually load) I've also read that giving java more than 4 gigabytes of ram causes issues. So my final question is this: What would be a good performance boosting jvm argument to use if one exists. Also, not sure if this changes much but, I use the ATLauncher.
If a list of mods is needed I can also provide that, as well as system specs.
Edit: When I'm on the title screen and quit the game, java is still running and I have to manually close it via task manager.
