Use the “Use Advanced 3D Settings” instead of letting programs choose their settings. Not your fault since those settings come out of the box usually.
Under “Manage 3D Settings” on the Left I would usually leave “Global Settings” on whatever it is that it comes out of the box, because generally speaking it’s much better to go for individual programs IMO since sometimes individual programs play more nicely with some settings (see my next point below).
Personally I would set “Power Management Mode” to “prefer maximum performance” or “Nvidia driver controlled”. Test a little bit after downloading something like Nvidia Inspector (that measure performance numbers on your GPU). Those usually push the card more than it might’ve with default settings. You can mess around with other settings, but honestly considering that your chip is much better than mine (Kepler is the successor to Fermi), I don’t think you’ll need to mess around with other things than just the power management. Remember to keep your laptop plugged in if you don’t want to kill your battery
Keep in mind that most of these settings will reset to default after a driver update, and I recommend backing them up with the Geforce 3D Profile Manager:
Apparently Nvidia Inspector has a profile saving tool as well, but I use this tool myself. See which one works for you I guess.
Let me know if you need any more help with this
EDIT 11:44 EST- Just remembered to say: you need to enable your Nvidia GPU under preferred graphics processor. Otherwise it might just use your integrated
