Even though this is probably not a glitch I thought i should report it 🙂.

@Daniel 4770k bother! Welcome to a world where bf4 give a higher average fps than minecraft!

@qmagnet read my previous posts where I compared the two versions side by side and received 100 less fps running everything the same except the version.

@Christopher it isn't just the people who have older computers. My PC is a 2400 USD pc built less than a year ago. I am currently facing this bug too 😞

Cleaned up my .minecraft folder. Graphic Settings: Render distance: 16 chunks, Smooth Lighting=Maximum Graphics=Fancy, Clouds=off, OpenGL=off, VRBO in 1.8=on VSYNC=Off Full Screen=Off Conditions: All other programs closed, and just restarted my pc. Tested in a new world generated in 1.7.10. In 1.7.10 FPS went from 140-350fps with an average of about 200. In 1.8 Fps went from 60-140fps with around 100 average.
My PC Specs are: i7 4770k @4.2ghz quad core, Asus Maximus VI Hero, 16GB of Ram, 2x Samsung 840 EVOs in RAID 0, 2x nVidia GeForce GTX 760, Windows 7. My average fps in Battlefield 4 is higher.

@Nick k This was fixed months ago, if you are having troubles update all of you graphics drivers.

Fixed for me in the c snapshot.

Confirmed with Windows 7.

He is a summary if what I think is happening.
There is a bug in the launcher that causes LWJGL to wrongly communicate with the launcher. This causes Minecraft, when it is launched, to not run as a game. AMD and NVida fixed this in their drivers somehow before the official release of 1.6, but Intel has not. This bug can be fixed by Mojang, or Intel, but updating the LWJGL will do nothing, as it is not fixing the bug in the launcher.
Edit: Brian download magic launcher and optifine (both are updated). Install optifine using magic launcher and set the ram in magic launcher to 256mb. Then turn everything off. I hope that this improves your fps to the playable level. Also open up task manager-details and select both javaw.exe's and make sure all have the cpu's selected in the affinity and set the priority to the maximum. This improved my fps by 200%

If Meri is right, then grum was right when he said that there was a problem with LWJGL. We just misunderstood him. It sounded like there was a problem with LWJGL its self, but instead it is a problem with LWJGL communicating with the new launcher.

How do we know that it is LWJGL 2.9.0. Has anyone tried updating to 2.9.0 then running the game on the old launcher and seeing if they get lag?

Yes, I agree, but this should be fixed. It is almost like Mojang is punishing people with integrated graphics card by saying that they can't fix it, and not even making an effort to.

@Meri can you decipher what @grum said? And do you know how to update the open LWJGL to 2.9.1 (it is out in their nightly builds section).

@Grum so if I update my LWJGL the I should be fine?

I recently talked to Intel on this issue. After a long and drawn out conversation with an Intel employee, he said talk to the game developer.

I have a quad core i7 mobile @2.2 ghz with HD 4000 and I have this problem.

Same problem here, and yes, if you use previous versions of the game on the new launcher, it lags.
