Hello,

 

I have Acer Aspire V3-571G laptop and in specifications it says that motherboard is NVIDIA GeForce GT 640M with 2GB dedicated VRAM. But when I play it says that laptop using only 128MB VRAM. Can you explain me, how to understand that 2GB dedicated VRAM. Is it possible to increase it, or do anything else to improve it? Because http://www.notebookcheck.net/NVIDIA-GeForce-GT-640M.71579.0.html here says that I should get 129-49 fps

(playing CS:GO) depending on graphics, but I dont. 

 
Thank you.

    We ship the V3-571G in multiple configurations, including one with the NVIDIA GeForce GT640M:

     

    • NVIDIA® GT640M with 2048 MB of dedicated DDR3 VRAM, supporting Shader Model 5.0, Microsoft® DirectX® 10.1, OpenGL® 4.1 or later, PhysX™, CUDA™, PCI Express 2.0/3.0, HDMI 1.4a (supporting standard stereo modes for 720p and 1080p), and PureVideo® HD with support for 3D BluRay.

    Where are you seeing that the video card is only using 128MB of VRAM ?

     

    Please be aware that we are only able to support the software and hardware that we ship with the system.

    We are unable to support or recommend any third party hardware or software.

    http://ipix.lt/di/QDB7/f.jpg Here it says, and in bios.. I am not really know the inside of computer or IT, so I am just asking what is that, and should it be like this.

    That is not an Acer website.  We do not know how it is attempting to get that information.

     

    Please note that it is detecting an Intel HD graphics 4000 card, not the NVIDIA GeForce 640M.

     

    Can you post the part number of your system?

    The system definitely ships with an NVIDIA GeForce GT / 2G-DDR3 (128*16*8).

     

    What do you see for display adapter(s) in Device Manager?

    Welcome aboard, Aurimus. The good news is that you're probably all right. Your machine is USING 128 megs of VRAM when you are checking it, but it is not limited to that number. Later, if you play a graphics-intensive game, your VRAM usage will go up.

    In device manager were both, GT640 and 4000 video cards. 

     

    Yea, I think it helps.

     

    Well, did some unistalls, and installs and now systemrequirements lab says I have 2 gb, as it should be. Thanks for you two Smiley Happy

    I know is too late, but i post it: you are right, you have two GPU: one in CPU, and another discret nVidia, and they are switching by load or application (game). Your Optimus driver was not working properly or your game (application) was not set to be open with the nVidia card.

    And another thing: in most notebooks with switching GPU-s, on battery (without charger) all aplicatios will always work on Intel GPU (nVidia GPU will be disabled).
