GT740m not being used - instead HD4600 Graphics

Zyre · Jun 7, 2014

Greetings!

I've literally been having the worst day in my life thanks to my laptop which refuses to utilize the Nvidia GPU.

My problem started when I decided to play a game on my laptop again after a few weeks of not playing on it. The game that I launched was Euro Truck Simulator 2 as I knew I would be able to play that game without issues.

When the game had loaded it was running like pure horse shit for some weird reason. Only 18fps on Ultra and 29/30fps on medium.

All confused I launched another game called Sniper Elite V2 and behold even that game runs shit. 25fps on medium. I found this to be really really weird as I had been playing PlanetSide 2 and Battlefield 3 on the laptop without even getting close to such FPS.

Even as comparison, my 9800GTX+ 512mb GPU runs Sniper Elite V2 at 40/50fps and that card is from 2009.

So I checked if i wasn't running on the Intel HD Graphics and it didn't, it was always running on the Nvidia card. I found this out thanks to Nvidia Optimus viewer.
I disabled the HD graphics (resulting in 1fps) and installing the OEM drivers without any effect.

I then did a complete clean install of the drivers thanks to Display Driver Remover and when it was all done I launched SimCity (2013). I got 25fps on normal settings at 720p running on the HD4600. When I launched with the Nvidia GPU I got the exact same result.

I have no idea right now how or what is happening right now and many can't seem to help me so I hope Tomshardware can!

(Laptop specs):
CPU: i5 4200M
GPU: Nvidia GT740m 2GB
RAM: 8GB DDR3
OS: Windows 8.1 64bit
HDD: 1TB 5400rpm SSHD

Model: MSI Gaming Series GP70 2OD-043NL

I hate these dual switching gpu laptops. They are SUPPOSED to switch automatically to the better GPU when it detects a game is started. The problem is it usually only works on like DirectX games, not openGL, not other game engines. Sometimes they have control panel software that lets you add in a game manually, or say, when this EXE is started, then swap the GPU.

Not sure where to tell you to begin as I'm not familiar with that model, but sometimes the geeks make hacks to let you switch it or to make it work better. Seen it for a few of the Toshiba models that have the same thing.

I know this will result in much less battery life, but have you went into your bios and disabled the Intel graphics entirely? If that doesn't work then there is likely something wrong with your graphics card

I was unable to disable it in the Bios. However I did another test with Simcity. I added the game in the control panel of Nvidia and did 2 test.

1 with the Nvidia card and 1 with the Intel GPU.

Results:
Intel GPU: 16fps
Nvidia GPU: 25fps

So this means the Nvidia card is running? I thought a GT740m should run in the range of 40fps? Can someone give some information?

It doesn't mean anything is wrong with the graphics card, it's getting the software to properly switch GPU's when it's supposed to, and now that the OP has messed with the drivers, it may not work at all.

Zyre :

Anyone have benchmarks of this card? I did a little research and the benchmarks seem to be all over the place.

getochkn :

I wasn't referring to a hardware malfunction. I was saying that then we know that there is something going on the the graphics card, whether it be the driver, etc.

This is just wierd. Battlefield 3 can be played at Ultra smoothly:

What is going on here. I stated earlier that I am able to switch between the 2 and installed the latest drivers after doing a clean removal. But the fps seems so low. 27fps for Simcity on normal at 720p.

In the meantime Battlefield 3 is seen being played at Ultra, higher then 720p and smoothly.

Edit:
I found some benchmarks: http://www.notebookcheck.net/NVIDIA-GeForce-GT-740M.89900.0.html

So..am I just being stupid or isn't my GPU that good at all?

I Had the same issue And posted my issue here and solved it on my own...
go to device manager and uninstall your gpu plus remove all the driver files then
again install and update your driver... work done.. 100% Working solution
