    Default Vision 3d 252b GPU questions

    Hi,

    For Vision 3d 252b some questions about the twin GPU configuration:

    1. Can the iGPU be disabled so that only the NVIDIA 540 is used?
    2. How to disable the iGPU?

    3. If both GPUs must be active then:
    3a. Which GPU is used for playback of live TV from Windows Media Center?
    3b. Which GPU is used for playback of Blu-ray using Arcsoft TMT?

    Regards,
    -tcc

    Thanks.
    Can't you use the Virtu control panel to turn off the i5 graphics? But not sure about the answers to the questions you pose regarding which progamme for which the gpu is being used

    EDIT; Just used TMT5 to see a blu-ray- swtiching it to force hardware acceleration causes the CPU to drop from 23% to 10%....

    I dont have a 252b unit and thus no experience with Virtu hense the questions. But here is what Ganesh from Anandtech said:

    >Yes, this (determining which gpu is used) is handled by Virtu. If you don't install Virtu, the 540M is the only one that is used. You need >Virtu to choose applications for which the iGPU gets used (commonly MediaConverter / any app for which you want to use QuickSync).
