Hey everyone,

 

Recently I purchased an Asus NN56VJ laptop, and had it customized to exactly how I wanted it. It came with an Nvidia GeForce GT 635M 2GB GPU as well as an Intel integrated 4000 graphics.

Supposedly when not using intensive graphics, it uses the Intel graphics, but when doing things like gaming it *should* use the  Nvidia one.. well as you might be able to guess, it doesn't. When I go in game it's a bit laggy and when I check out the graphics it says I have 504mb of video space!

 

Can anyone help me to figure out why this is happening/how to change it?

 

Thanks,

Visi

Under Device Manager, is your 635M listed under the Display Adapters section?

Modern day laptops that have hybrid graphics have a toggle switch. You should be able to find it in the nVidia control panel, or under some other settings panel somewhere. Consult your manual.

I ran into this same issue with my laptop's 680M. It's a combination of not recognising the Nvidia card and of an issue GTA4 has with cards that have 2GB of VRAM or more. Here's what you do:

 

Go to the NVIDIA Control Panel and confirm that the setting for GTA4 is "Dedicated: NVIDIA GPU" (or similar).

Apply and close.

 

Next, add the following command line launch parameters to GTAIV's shortcut (or as extra launch parameters in Steam): -nomemrestrict -norestrictions

 

Feel free to launch. Intel HD 4000 may still show as the GPU. Don't worry about it, it will be running off the NVIDIA card.

Hope this helps.

Thanks for your suggestions and support everyone!

 

My 635m was listed as a display adapter in Device Manager

 

Unreal: I tried any possible combination I could to get it to work and it still ran off the Intel Graphics, but thank you

 

Papa thanks, that helped a lot!

 

Many thanks to all that threw in their help! It's still a tiny bit laggy (but what laptop doesn't lag)
Thanks!

 

EDIT:

So I just noticed that it still says I only have 504mb of GPU memory and not 2GB? Any ideas?

Don't worry about it. I have a 4GB GPU and it shows 3064MB in GTAIV.

Haha well alright thanks! Any tips for speeding it up? I'm still getting a tiny bit lag and hoping that I can find a way to fix this?
