How To Set My Nvidia Graphics Card As The Primary Graphics Processor For Games?

I've tried just about everything, and have looked at several forums for help, but haven't yet found any solution to my problem.

Up until about a week ago, I've been able to run most games fairly well, but performance has recently deteriorated(CSGO has dropped from 200+ fps to below 60 fps; PUBG has dropped from 30 fps to around 12 fps). The game would also stutter with black-flashes, until it alt-tabbed me out of the game. I assumed there was a problem with the Nvidia/Intel drivers and updated them both, but the problem persisted. I then realised that the onboard-graphics was being used for games as apposed to my GPU.

Upon Googling the problem, many forums suggested opening Nvidia Control Panel > 3D Settings, and changing the "Preferred Graphics Processor" for each program. However, this option/drop-down does not appear for me. My monitor is plugged into my Graphics port and not my Motherboard, which is the primary reason for this option to not appear, so I am unsure why I don't have that option available. My PC detects and recognises the existence of my GPU, but refuses to use it for any games that I play. Does anyone know of any solution?

Note: When I access the Device Manager > Display Adapters, and I disable the on-board graphics, my PC reverts to using the GPU and my games function smoothly. However, I have been told that disabling the on-board graphics is a bad idea.

Specs: Processor - Intel(R) Core(TM) i3-4150 CPU @ 3.5GHz GPU - Nvidia GeForce GTX 460 SE Motherboard - Gigabyte H81M-S2PH RAM - 8GB OS - Windows 10, 64-bit
 
You will use the GPU at which you have connected the monitor, or am i getting this wrong and your on a laptop? Im asking because the parts you listed are not laptop parts but desktops will not automatically switch GPU as you need to physically connect the monitor to the GPU you will use.

On a desktop and if using a discrete GPU, you should disable onboard GPU in the BIOS.
 
From what hes put on here he has a desktop motherboard 1 hook your monitor up to the discreet graphics card if that dont work ok go into your bios and pick your slot pci-e disable onboard...
 


Yes, my bad. I just realised now that you can only select the 'preferred graphics processor' for laptops in the Nvidia control panel.

I went on to disable the on-board graphics in the BIOS menu, which stopped my games from freezing and stuttering, but it still didn't perform as well as it used to (around 100fps vs. 250fps in CSGO), and the frames continued to drop as I played. I re-enabled the on-board graphics and still have the same problem. Maybe the card has become faulty and just doesn't perform as well as it used to?
