Frame-rate drop in 14w28b

Cannot Reproduce
It's even better for me than in 27b

Can slightly Confirm (had FPS Settings set to max. 60)

• 27b: 130 FPS

• 28b 80-20 FPS

It's really not much for me, but as far as I know, the cause has been found.

Please attach the complete output of the "Development console" which can be found on the second tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

Can confirm, my frames dropped form around 70 to 30. Upgraded from 27b to 28b.

Could not do the complete. 20,000 letter limit sorry

I also play on unlimited frame rate. not sure if that effects it

Can't wait for the fix because the lag in my spawn chunk is unbearable! 14w28b

Jungles are the worst.

I can also confirm this! Also, glad I'm not the only one.

I have the same problem. I'm usually at around 50-60 fps, now, even with everything at a minimum, I get 9 fps. It's unplayable right now.
