I had updated my minecraft to 1.6 yesterday, and I thought, "oh, this'll be cool." But, uh, yeah, no.

In 1.5.2 I could run the game with the most advanced settings; in the most occupied servers; have multiple windows (skype, quicktime, internet, ect.) open, and have no lag whatsoever.
Now I have to lower everything as far as it can go, and I still get massive lag.

I'm using a 2.6 GHz Intel Core i7 4GB Macbook Pro (mid- 2012 version)
And I have the NVIDIA GeForce GT 650M set as my default graphics card, but I also have the Intel HD Graphics 4000 built in.
I'm using the newest version of Java (JDK8 64bit)

I had lag when I had just created a world, with nothing added at all. Like, the fps were down to around 15-20. I can usually run way higher than that.

I've seen some articles about people with similar problems, but any solution they have doesn't help me.
Seriously, if I could get some help I'd appreciate it cause I'm dying here e.e

I've pretty much tried everything I can find, and no luck. So I'm kinda just gonna give up on the 1.6 launcher all together, and just stick with 1.5.2 because even if I tried 1.5.2 in the 1.6 launcher it sucked, but the 1.5.2 launcher works amazingly without lag at all. So it's obviously not a server/computer problem, it's the launcher itself, or at least the launcher cooperation with my laptop. Either way, I'm sticking with the 1.5.2 launcher.

I have also noticed that the sprint in 1.6 is way off, and when I say that i mean I try to sprint, it is delayed for about a second, and then I sprint. If you know any solutions to this please tell me, cause being a big MCSG (Minecraft Survival Games) player, this is a very big problem.

Ok, thank you! Hope that the problem gets fixed in the future.
BTW I subbed to your channel!
