High performance gaming laptop but not high fps?

70-90 FPS is "high performance", or close to it. No need to complain, you probably can't see more than 60 FPS with your eyes anyway…

GTX960M… Your on a laptop… Be glad your getting that with that little game… Minecraft…

As for what you say is a high performance " gaming " laptop… If you spec out your video against what is recommended just to play GTA V… According to benchmarks.

your in the medium to medium low settings.

So be glad that an older game like minecraft is giving what you are getting…

Watch this video that runs very good with GTX 960M

i think HD 4600(which is cart of processor) running on since it uses that instead of GTX 960M

Disable it from My Com/This PC to right click>Device Manager>Display Adapters> If the HD 4600 is enable disable it and then try again/Uninstall the HD driver, rather than just disabling it (restart needed).

If that doesn't help go to Nvidia Control Panel(right click on your desktop background and you'll find it) > 3D Manager and then choose the game and make it run on Nvidia graphics.

You don't say which OS you are running (I have not tried Win10 yet). I have an older i7-4700MQ, 8 GB RAM, GTX 765M which is 2.4 GHz, but I run Linux which automatically uses turbo mode (up to 3.4 GHz I think) and I normally have minecraft in fancy settings set to throttle to 120 fps. So it mostly runs 120 fps @ 1080p and may dip to 110 fps. But your laptop screen is 60 Hz anyway, so as long as your fps stays at or above that, you should not have any problems.

Your GTX 960M should comparable to my GTX 765M, if anything a little faster for most things. Some reports say the GTX 960M is comparable to the GTX 750 Ti that I have on my desktop PC and that also limited to 120 fps @ 1080p just occasionally drops to 119 fps on an old i5 650 3.2 GHz CPU w/8 GB RAM.

In Windows if you do not specifically run an app that puts your CPU into turbo mode, maybe your CPU is actually running at 2.6 GHz. Or maybe it depends how much memory you give java for minecraft to minimize reloading chunks. The default is 1 GB max and 128 MB minimum, and for my laptop in the Profile in the launcher I gave it -Xmx2G and -Xmn1G (my desktop is set to -Xmx2G with no minimum set).
