Hello there. I just bought a new Acer Aspire v5-573G yesterday. It has an Intel Core-i7 (1.8Ghz) 4th generation processor, 8GB of DDR3 RAM, 1TB Hard-drive and an Nvidia Geforce GT 750M Graphics card with 4GB Dedicated V-RAM. The BIOS is InsydeH2O Version 0.3.73.06V2.22. This machine comes with a DVD containing all the drivers for it's hardware pieces.

I installed a Windows 8.1 Enterprise 64-bit on my new machine and everything went smoothly and are working perfectly, except for the graphics card. However, Windows installed all the drivers correctly even the touchpad, bluetooth...etc and they are working fine. It installed the Intel graphics driver, but it didn't install the driver for Nvidia graphics card. so I installed the driver manually from the DVD and it got installed successfully, without any sort of errors, but when i go to Dxdiag.exe "Display" Tab, it doesn't show any sign of an Nvidia Geforce graphics card , it only shows the details for Intel(R) HD Graphics family and indicates that the "Approx. Total Memory is: 1792 MB" as if there isn't any other graphics card. I went to Nvidia Control Panel/System Information Tab and there it shows all the details for my Nvidia graphics card and states that "Dedicated video memory is: 4096 MB DDR3".

I installed several games and when i run them they just don't open up and give errors like "You don't have enough video memory and etc..". some games do run but with very low graphics quality as if I didn't have any video card installed. I did everything I could to solve this issue,  I even went to Nvidia website and by allowing the website to auto-detect my graphics card model it recommended me the appropriate driver, so i downloaded it and istalled, but still i see no difference and face the same issues. I have repeated the above procedures like 5 times and istalled different versions of Windows 8 but nothing happens, it all end up the same! I have no idea what to do! please help me.

    dxdiag doesn't really support multiple GPUs, so its not reliable.

     

    If you really do have the drivers installed successfully, then you should be able to rightclick applications and shortcuts to them and have the option "Run with graphics processor ->", where you can pick either the Intel or Nvidia gfx card to run said application. Within the nvidia control panel, you can also set the behaviour for each application individually (what it should default to), so that you dont always have to start via rightclick to run in another mode. Games however should already be set to the nvidia GPU.

     

    Also, running dxdiag.exe with that rightclick thingy does still display Intel HD as the grahpics family, however the available memory jumps from ~1GB to 4GB (its a GTX850M in my case though).
