    Do we or can we get a thread that covers all laptops with a MUX switch?

    This feature allows the user to use Optimus or Gsync.

    As far as Clevo based systems go:
    • P65x (e.g. P650, P651) systems = 15"
    • P67x = 17"
    • PA71 = 17"
    • ?
    And, technically, MSHybrid and Optimus are different implementations.
    Clevo uses MSHybrid.

    The MSI Titan I used a few months back had this feature too.

    There has to be more than just a handful, right?

    It would seem like these would be the go-to laptops for so many people for this feature alone. Likely the main reason it’s not is simply because the majority don’t realize it exists.

    So with that said, what is stopping manufacturers from implementing this in all laptops with dedicated GPUs with intel CPUs? Is it expensive? Are there licensing issues?

    Truth be told my last Clevo was the p650 and I stumbled across this feature within the bios (factory set with mshybrid off) and had no idea this was an option.

    After using a machine recently with Optimus I realize how great having both dynamic sync for gaming and Optimus or MSHybrid for times when your laptop is a laptop.

    Alienware M17x R3
    Alienware M17x R4
    Alienware 17
    Alienware M18x R1
    Alienware M18x R2
    Alienware 18

    Optimus mode -> BIOS GFX set to SG
    Discrete mode -> BIOS GFX set to PEG
    Intel only mode -> BIOS GFX set to IGFX

    None support g-sync

    Interesting! What’s the benefit of switchable graphics without any dynamic sync features?

    I can only think of two. Pascal can use FastSync but many of the laptops you mentioned date back to previous gpu generations. Begs the question “why?”

    The other reason is that Optimus at times has some stuttering and hitching. Almost random and driver defendant.

    What else?

    Thanks for participating in this random thread folks

    Having Optimus induces a 8 - 10 ms of display time, which is a lag. It kills half of the power of a GPU

    Having a switch, on the other hand, doesn't do any damage or cause any issue. At least in theory.

    The idea was for better battery life through optimus, get good battery when disconnected from AC, and good performance when connected to AC. Unfortunately optimus does not always work as well as nvidia says it does, but at least it is an option. For certain alienware models, it also allows us to run pascal cards in a LVDS computer since intel hd 4000 and intel hd 4600 does edp -> lvds signal conversion. It's always good to have more options available than to have less customization.

    according to meaker, clevo not implementing it to save cost on the mobo, honestly prob not much savings at all they can easily remove finger print reader which I never use.

    iGP is only there for backup purposes and when running on battery though, it would not be a problem for 99% of usage scenario until power goes out. then i'd be watching movies on iGP and 1 CPU core hope that it'll last for hrs
