Wrong Graphics Card Being Used?

[ksnumedia]

Hi I think my GPU is not being used for games I have installed on my computer.

I have a Nvidia GTX 750 ti, which should run Crysis 3, Prey, Titanfall 2, and Doom 4 pretty well, even if not at the max settings. The problem is, the card is definitely underperforming or not being used. On the lowest settings, I get 25-30 FPS for Crysis 3, ~5-15 variable for Prey, Tfall2, and D4.

I've seen videos of the GTX 750 ti running these games at medium to high with FPS in the 40s and 50s, Crysis 3 seeing the best performance on High to Very High setting.

I was just prompted to ask because when I tried to launch Halo: Combat Evolved, it was detecting that my onboard Intel HD graphics was used. So I'm wondering if the onboard card is running these games instead of my GPU.

Is there anything I can fiddle with in control panel or device management? Because my monitor is plugged in via USB adapter to my PC, I don't know if I can go out and buy a new one since this machine ate up quite the sum of money already.

EDIT: I just checked GeForce Experience and it is indeed detecting these games. So I'm not sure why the card is not being used - should I just disable Intel HD Graphics so the PC is forced to switch to Nvidia? I just don't want to screw anything up because I did not connect my monitor to my GPU.

Plug your monitor into the gfx card directly. Not thru a USB adapter.

are you on a laptop or a desc pc? cant really figure it out from what you wrote.
anyways when having more than one raphic card in the system go to geforce control panel/experience and you should be able to decide on a per game basis wich card you want to use that game with.

If your monitor is connected to one of the onboard graphics outputs, that's what you are using...; connect your monitor to your GPU. (It would be funnier if I had not accidentally reconnected my monitor to onboard myself, then wasted an hour and noticing horrible perfomrance!)
