Laptop wont use Dedicated GPU.

post #1 of 22
Thread Starter 
Ok so I Just got in my Lenovo y410 has 755m gpu. When I try to start up any game it still trys to use the HD4600? Wondering why the gpu doesn't kick in? If anyone has any knowledge or help for this please feel free to share. I would appreciate any help with this.

How do you know the 755m is not running?

Does this laptop support NVIDIA Optimus technology? If so, it might be a misreport due to how the tech works.

Well like Skyrim for example when I go into the options for skyrim. it don't even list the 755m gpu its just lists the intel HD 4600 in the graphics options.

if you open up GPU-z while in game you can watch which chip is being utilized. thats what I usually do to test it.

Again, does your laptop use Nvidia Optimus? If so, it might be a misreport by the game since it can't detect the 755m even though it is processing the video.

With Optimus, all video goes through the iGPU. When it's not GPU intensive workloads, the iGPU does all the work and the dGPU sleeps. When it is GPU intensive, the dGPU copies data from the iGPU, processes, and feeds it back the iGPU. The video always comes from the iGPU even though it may not be doing the work.

Like someone said use GPUz to see what your gpu usage is.

TechPowerUp GPU-Z v0.7.5

You'll have to download this (like 1.5MB) and see for yourself.

You may be interested in Virtu MVP. For this very reason you can set which is your primary GPU. What if possible I would suggest to due even being a notebook disable integrated GPU and use dedicated. Now other will argue its a laptop and not wise, but It sounds like you bough this for gaming, so you have to know gaming notebooks don't normally last long power wise anyway and i'm guessing you normally have it plugged in anyway. You may need to open up your nvidia control panel and see what optimius is doing its supposed to do what Virtu pretty much does is switch on the fly between Primary and Secondary Graphics.

Ok I figured out why it wasn't showing up in skyrim. It was the new driver I downloaded, soon as I uninstalled that driver it pulls up fine now.
