Laptop Won't Detect GeForce Graphics?

Hello everyone,

So I bought my gaming laptop from xoticpc.com, it was a Sager NP7352. I chose to buy the NVIDIA® GeForce® GTX 765M 2,048MB PCI-Express GDDR5 DX11 w/ Optimus™ Technology.

Earlier today I was curious to see why I was lagging when playing Battlefield 3 since I was told the laptop could pretty much run the game at max graphics with this video card. I wasn't even close to playing it at Max Graphics, so I was curious and went to see what card I had in my laptop.

I current have Windows 8 64bit installed, so I went to device manager and it showed that I was using Intel(R) HD 4600 graphics. I began freaking out and called customer support and they told me that it was the optimus technology that was showing this and that whenever my computer didn't need to use the GeForce graphics card, it wouldn't use it and instead used the intel. That cleared things up but I was still curious to see why I was lagging.

I went to the GeForce website and went to the "Automatic Update" finder that pretty much finds out what drivers your graphics card uses and if an update is needed our not. It said that it could not detect any nVidia Products on my laptop. I then downloaded the NVidia Control Panel that you can run on your desktop. However when I went to install it it told me that no nVidia products were found on my computer. I was beginning to get very frustrated since I was sure that it shouldnt at least recognize that I had the darn graphics card. I have found no evidence on my laptop that I currently run/own the GeForce graphics card.

Can anyone in anyway help me determine a way to make sure I have the GeForce graphics on my laptop? I would be very bummed to find out that I ordered it with the graphics card and it was never even installed. Any help whatsoever would be appreciated, thanks!

The GPU is integrated into the mobo so it most definitely is installed, but nothing is showing up because you haven't installed the driver for it yet. Go here and manually find and download the latest driver for your GPU and OS: Drivers | GeForce

 

he needs a modified INF file.

OP, see if you can follow this step-by-step. if not:

1.) go here
2.) choose your drivers (assuming you'll go with 331.40, the most recent WHQL)
3.) download both the drivers and the modified INF file (you may need to 'right click + save as' the INF link depending on your browser)
4.) after extracting the drivers, replace the existing INF file entitled "nv_dispi.inf" with the INF file you just downloaded separately
5.) run setup and now the installer should recognize the dGPU

did you purchase the machine without an OS?

 

So you're telling that a GPU which has been available for all of summer still doesn't have officially supported drivers? How have other 765M owners been managing? They've all been using modified .inf files to install the latest drivers? I find this very hard to believe, but it's extremely sad if true.

 

it's a switchable graphics/optimus thing or something. obviously all of nvidia's current hardware is driver supported.

 

Download these drivers, they work fine with 765m:

Drivers | GeForce

Make sure power options are running at "high performance" (left click the little battery icon in the lower right corner, click "more power options", expand "hide additional plans" and choose high performance).

Then right click desktop and bring up nvidia control panel. Click "manage 3d settings" on left, click program settings on right, pull down the menu and choose Battlefield 3 or "bf3.exe" and set it to use nVidia Graphics.

Also the 765m can't play BF3 at max settings at 1080p. Mostly high/ultra config though. See this video:

Also the 765m can't play BF3 at max settings at 1080p well it can, just it can dip below 30FPS periodically. High config I can limit FPS to 58 and it pretty much stays pegged at 58. See this video:
