Minecraft: Stuck on 62 FPS?

I'm Having some trouble with my Minecraft Framerate.
Few days ago, my minecraft was running at 150-250 fps (On max Settings, Fullscreen Mode)
Now, it's like 60-62 Frames (Only Fullscreen)

It happens in Fullscreen mode only. When I'm running Window Mode, it's giving me about 150-200 fps.
By the Way: I've V-Sync off.

Graphic Card: GeForce gtx 765M
Notebook: msi gs70 stealth (8 ram version)

That's cute, on console we're playing at 720p 30FPS.
Get a better computer

A) Notebook. A Notebook isn't much better than an actual notebook, with paper and pens and shet. If you want to play games with a ridiculously high framerate, get a desktop.
B) The difference is really not important. The human eye perceives life at 24 fps. Anything higher just results in faster reaction timing. 60-62 is plenty for anybody, don't let PC salesmen persuade you otherwise.

My suggestions are try to close every window but minecraft, go to task manager and right click java.exe(minecraft)and click set piroity and set it higher than normal(make sure your running minecraft when doing this) if that does not help then I suggest you tweak your pc settings
