Lag Spikes / FPS Drops

Ever since I updated to the Snapshot 13w04a(also 13w03a), I've had massive FPS Drops in the Overworld, which has made me pretty much unable to play. This doesn't affect any other dimension, as I have about 96-160 FPS over all in the end, and 110-180 in the nether. Back in the later snapshot (13w02b) I never had this problem. But now I can't get more than 16FPS in the overworld.

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

This is the Crash-Report

Switch to the default texture pack and see if that changes something.
And please attach screenshots of 13w03a and 13w04a with the F3 debug screen shown.

Alexander Söderberg

Just a couple of minutes after each other, I couldn't use the "Attach Screenshot" so I just uploaded it as a file.

kumasasa

Sorry meant screenshots with the Shift-F3 debug screen (and please do not cut off the screenshots).

Alexander Söderberg

Alright, but I actually didn't cut them off this time, since my computer takes weird SS's. I'll see what I can do.

Alexander Söderberg

These are the ones with Shift F3

May be related to MC-2176.

I've changed the affected versions, and added 13w02a, since the FPS is alot lower there too. I added a screenshot of a weird CPU-thingy, and I got reasons to think that the unspecified (Seems to have something to do with the particles, even though I have them on decreased) is causing it. Any thoughts?

Duplicate of MC-2176.

This is not a duplicate, since the other ticket is about FPS going down for a couple of seconds, then going up again. Mine stays down for the whole time, thank you.

It could just be an problem with your computer. I know my friends computer does this but his old one didn't. It is an hardware or java issue. So this is an duplicate.

Alexander Söderberg

How could it be my computer, if it has never, ever, done this before?
