Hi i keep getting crashes in minecraft singleplayer and it never happens when i play multiplayer. I have a pretty decent laptop and it runs multiplayer perfectly no problems at all, but when i play singleplayer it will be fine at first and then like 2 minutes in it will start to get lag spikes and the lag spikes will get worse and worse until minecraft just crashes.

Here's the crash report:

I would Recommend removing your "Session ID is token" To avoid getting banned on any servers

im trying to fix singleplayer not my hacked client -.-

Thats not the point.. he's saying your session token is in the log. Other people may be able to use it, I'm not sure.

We don't support hacked clients here. Buy the game.

well considering that the log has a failure to authenticate in it, I think the hack is a crack.

Otherwise the fix is obvious.

No i bought minecraft, but that doesnt explain why minecraft is working perfectly in multiplayer, i can play for hours with no crashes, but when i play singleplayer i can only play for a few minutes then it turns to crap.

Thats is the thing I was saying that If you ever chose to play multiplayer you may be banned because of leaving you're Token in there and other people can log in as you

the render distance is too high.

Since this setting is over ridden by the server in multiplayer it's why only single player has problems.

Whether this might be fixed by increasing Xmx or whether the computer is never going to handle it can't be determined from just this info.
