    Microsoft Windows 10 (build 15063), 64-bit

    Can I enable my laptop to use 1 GPU for everything? (Laptop has 2)


    Hello
    Recently I've discovered that my laptop has two graphic cards:
    - AMD Radeon HD 7600M Series
    - Intel(R) HD Graphics 3000
    I'm pretty sure that games have been using the Intel GPU, as my laptop's been underperforming.
    I read online that my laptop has 2 GPU's to save power, but I really don't care about that since I almost always have my laptop plugged in when gaming. My question is, is there a way to make my laptop use the AMD GPU for everything I do on it?

    Thank you in advance

    I would recommend you determine your exact ACER make and model number so we can look at what options may be available in your specific BIOS. You can download HWINFO (portable), run it, and post the results (like so):

    On my ASUS K75DE Laptop its done in Catalyst Control Center. I have a AMD Radeon HD 7660G + 7670M 1GB DDR3 VRAM. There is no BIOS setting to lock in one or the other. Not that I can find anyway. The BIOS on it is pretty basic and restricted.

    On you rig, in the Catalyst Control Center don't you have to specify it on a game by game (or program by program) basis? And, if so, have you tested it to ensure it actually works because some have reported not having complete success in that area. Also, I hesitate to disclude all manufacturers from providing an option in the BIOS to discretely select a unique graphics card... even though the normal choices might just be integrated or switchable.

    I just leave it on the defaults. I don't game on my laptop. I just know that's where you change which one is used on my laptop. For me its basically as follows, on battery its the 7660G and when plugged in its the 7670M. And i'm fine with that. I'd have to go have a look see, to see if there is a global setting. I'm on my desktop PC at the moment and my laptop is all packed away in its carry bag. If I get a chance latter on I'll have a look.

    OK, thank you for your detailed response. Sounds like you are using it at defaults; however, I think you can force it to switch by game or program. Unfortunately I don't have a switchable graphics laptop to test myself. Thank you for your intent to follow up with your results.

    regards,

    Yes, I can set it to use a specific GPU for a specific program/game in Catalyst Control Center. I'm lucky in that my setup is AMD/AMD. And not Intel/AMD or Intel/NVidia. The mixed GPU types can be tricky to setup the way you want them.

    OK, then maybe the OP can use your method to select the specific games or programs; however, as you have stated, the mixed Intel/AMD solutions do not always work that well so I would still like to see what options are available in the BIOS.

    In general, no you can't as there is common hardware to both GPUs in a Laptop.

    It is not the same hardware arrangement as a desktop with a separate Graphics Card, that has two sets of outputs one for the integrated Intel HD graphics, and another set for the installed PCI-E Graphics Card.

    The M series of Graphics Cards main point is low power consumption as they are in Laptops, that also results in less performance than the Desktop variant.

    Here is a comparison between Nvidia's Optimus and AMD's Dynamic switchable graphics, this is for Notebooks and M chipsets (Desktop users note....).

    That dates from 2011

    A summary is basically, the integrated GPU is used by default in cases when the application is not recognized.

    Yeah, I'm pretty sure that that won't work since its intel/AMD. But I will try that if the BIOS doesn't give me any option.
    BIOS
    InsydeH2O Version V1.17
    Version
    Acer V1.17
    Manufacturer
    Acer

    That's my BIOS info. I've also included a screenshot of the summary.Click image for larger version.
