I just bought assus k555l with Geforce 940m gpu and the laptop keeps using the integraded one, i tried everything set to high performace usage in control panel, started with high performance but he keeps using that one
Added (1). Dota2 and PES lag and use integrated while minecraft uses nvdia, i disabled the integrated then i can't use nvidia control panel
It will only use the Nvidia graphics when higher performance e.g. Games it is needed. For every day usage it is not needed, the integrated graphics are fine for this and saves power and improves battery life
Go into the device manager and disable the onboard graphics profile.
Confirm with the manufacturer that the 940m isn't an integrated chip. This is actually a configuration that happens. I had a laptop once with an integrated GeForce card and this frustrated me until it was explained how to test it on my machine by Dell support to prove it was the 800 series GeForce I bought.
