I have a computer with 8GB of ram. With this I can play with a distance of 16 chunks (200+ fps), and now I want to try to play with far distance. However, I need to increase the RAM amount in the profile properties tab.
When I set the ram to
2G, the game won't run.
Java settings for the profile:
javaw -Xmx2048 -Xms1024
I have installed 64-bit java in my computer.
Why I can't set more RAM?
If it is useful: The profile is vannilla minecraft (no mods). It doesn't start.
