How to turn off Optimus on your Gaming Laptop

Each laptop brand has a different way of using the MUX switch to enable or disable Optimus. This guide will show you where the setting is for all of the main gaming laptop brands.

How To Tell If Your Gaming Laptop Has A MUX Switch

Different laptops from the same brand may have different options to what’s shown here. In my experience, for the most, part they’re generally the same. That said, differences between generations of hardware are more common.

I’ve listed all gaming laptops that I’ve personally tested and covered if they do or don’t have a MUX switch here. This guide teaches you how to check for yourself if you have a model I haven’t covered.

Click on your laptop brand from the list below:


Acer

Open the Predator Sense software and select the cog icon from the top right. Click on “Discrete GPU only” to make the change. A reboot will be required to complete the process.

Alienware

I’ve only had the Alienware m15 R5 to test with this feature, and it does not have any front end software to use the MUX switch. You need to boot into the BIOS (power on and keep pressing F2). Go to the Advance tab and select “Enable Hybrid graphics” with the arrow keys and press enter to change it to the desired setting. Once complete, go over to exit, save the changes and leave the BIOS.

Aorus

Open the AORUS Control Center software. Select the “Manager” tab and toggle the “Graphic Switch” as needed. A reboot will be required to complete the process. Gigabyte laptops may be similar, but they are often resold Clevo models, so check the Control Center software.

Dell

I’ve only had the Dell G15 5515 to test with this feature, and it does not have any front end software to use the MUX switch. You need to boot into the BIOS (power on and keep pressing F2). Go to the Advance tab and select “Enable Hybrid graphics” with the arrow keys and press enter to change it to the desired setting. Once complete, go over to exit, save the changes and leave the BIOS.

I still can’t find it!

If in doubt, just look through the settings available through the laptop’s primary control center software. If there’s nothing there, have a look through the BIOS. Most laptops that let you toggle the MUX switch through software also give you the option through BIOS, but not necessarily the other way around, as is the case with the Dell G15 5515 mentioned above.

    Hi Jarrod,

    I have a Legion 7i (10865H/2080s) and the only time I was able to disable Hybrid mode was fresh out the box – no matter what drivers I’ve tried since then, when I disable Hybrid mode I get a blank screen on boot (can still get an output on an external display, so I can revert it back).

    Ever seen this issue? There’s a few similar stories on Reddit and such, but no concrete solution that I can see! Driving me up the wall, considering I only ever use it when attached to the wall!

    • Jarrod

      I’ve heard of similar problems but only when people do the opposite and disable the iGPU. I suppose for what ever reason the discrete graphics isn’t connecting to the screen, not sure why, could try DDU + clean driver install and make sure you have the latest BIOS, after that probably time to contact Lenovo support.

  • Willy Anugrah Cahyadi

    I am using Acer Aspire E5-576G-57NY that uses Intel Core i5 8250U (Intel UHD 620 graphics) and Nvidia MX150. To my surprise, the Acer PredatorSense app works wonderfully to disable the Optimus.

  • Gabriele

    Hey Jarrod,
    Like you I’m passionate about laptops and hardware and love your videos (I’m also in Melbourne btw).
    Did you find a way to enable the advanced BIOS and undervolting on the newer Lenovo Legion 7 (and 7i)?
    Stupid new Windows and BIOS update disabled undervolting 🙁
    Tried with the Fn+R/N and also Fn+All Keys trick but no luck. Also tried Fn+F2 on boot but nope 🙁

    • Jarrod

      Hey, unfortunately I had the Ryzen Legion 7, so no undervolting on Ryzen as far as I’m aware, haven’t had t he 7i yet to try. Haven’t heard anything about the advanced BIOS though, I just confirmed the combination that worked previously with last gen didn’t work with current gen, so not sure if it’s changed or just not there.

    I have an HP pavilion gaming laptop 15. It comes with a 150w power supply, but I can get an HP omen 200w power supply that fits and has the correct voltage, amps, etc.

    My GPU maxes at 51watts power draw right now.

    Will the extra watts from the omen power supply allow the GPU to draw more watts and thus improve performance on games that need the additional GPU resources?

    • Jarrod

      I do not know, but probably not, most laptops come with the right size brick to run the hardware maxed out. It may be the case that the power limit of the GPU isn’t max though, so potentially flashing a different VBIOS with a higher power limit would use more power than the stock brick could handle, but that’s pretty high level stuff and not without its risks.

  • Orlann

    Hello, I just wanted to ask if I use an external display to bypass the optimus in my laptop, can I still have the onboard display as my primary display and have the optimus disabled at the same time? Or do I have to always use the external display? I’m have ASUS TUF Gaming F15 2021

    • Jarrod

      I am not certain but I don’t think so, I have to turn off the laptop screen when doing that otherwise if the iGPU is still active you don’t seem to get the FPS boost.

  • Calvin Ray Di Bartolo

    I have a Dell G7 17 7790 with RTX 2060.

    So, I don’t have a mux switch, specific ports *are* directly connected to the GPU — specifically the Display Port and the Thunderbolt 3 port. The HDMI and built-in screen run through the iGPU/Optimus.

    Yes, if you buy the appropriate eDP cable (40-pin) and screen you can absolutely upgrade your screen to 144hz — I did read somewhere that there’s a version of this laptop with 300hz.

    Yes, if you remove your secondary hard drive (or never had one to start with), you *can* install the 90Wh extended battery, even though the 60wh is 15v and the 90wh is 11v, *it does work*.

  • Bernardo

    Hi, i have a Predator PH315-53 with an RTX 2070 Max Q and a I7 10750H and i can’t find the “Discrete GPU Only” in the acer PredatorSense menu, i don’t know why because the laptop is brand new and i want to use the 144hz display to play my competitive games, i made some testing and i am losing around 120 FPS in Apex Legend in comparison with my external 60hz monitor. Maybe it is an older version of PredatorSense in the image or my laptop is incompatible with it?

  • Marx

    Does the Acer Predator Helios 300 PH315-54 QHD 165Hz RTX 3060 model has the MUX switch ?
    if not can i turn on and off the optimus when required?

    I have seen your Acer Predator review the model you used was 144Hz FHD RTX3070
    does this laptop also have same problems that you have mentioned in the video?

  • Mike

    I’m glad to have found your web site. I only wish it had been sooner. I had no issues with my previous notebook, a lower-tier Lenovo. Its replacement, an MSI GE75 Raider I bought earlier this year, apparently doesn’t have this MUX switch. With certain games, I am forced against my will to use Intel’s junk GPU instead of what I paid dearly for. How is it that this situation exists in the first place? It’s not something I would have even been on the lookout for, just as I don’t worry about auto manufacturers forcing me to drive at half-speed on certain highways. It just doesn’t make sense.

    • Jarrod

      It’s just the tradeoff for better battery life, in most cases gaming performance is still decent, just not optimal, but it depends on the game/settings/resolution.

  • Mike

    I understand the reasoning for having a setup that can switch between the two, for people who are actually going to be using the battery. However, not everyone is going to use a notebook that way. I don’t. Regardless, there’s simply no excuse for not giving the hardware owner the option; he or she is the one who ponied up the cash. There are games that flat will not use the Nvidia GPU at all. Mostly older games, but they still run horribly on the Intel POS. That’s how useless it is, which of course is the reason people spring for the Nvidia GPU in the first place. They should have designed it in such a way that we have complete control over our own hardware. That’s the bottom line. It’s just unacceptable to me. Should be to everyone, on principle if nothing else. People need to start putting pressure on these companies.

    Hey Jarrod,

    I am using an Acer Predator with RTX 3060. However, the option to use only discrete GPU is not shown in the advanced setting in the PREDATORSENSE app. Any idea what would be the cause?

  • Pete T.

    Hello Jarrod,

    Great information! Since Optimus is specific to NVIDIA cards, how does this work with AMD Radeon cards? I am specifically asking about Lenovo Legion 5 laptops with the AMD 6600M GPU. Do these laptops also have a “Hybrid Mode” that can be toggled on/off? Is AMD’s Switchable Graphics equivalent to NVIDIA’s Optimus? Any major differences between them that one should be aware of? Thank you.

  • Alex

    Asus TUF dash F15 2021 seems to have this option to disable the IGPU, however i do not know how efficent this is. or if this actuall does stop the iGPU or not.

    • Jarrod

      It does not have the option, you’re probably confusing it with the opposite function where it disables the Nvidia GPU and only runs on the iGPU to maximize battery life.

    • Jarrod

      Yeah iGPU off mode means the 3070 will show in task manager as normal. With iGPU mode on, the 3070 will be gone. It has nothing to do with disabling optimus to get a speed boost unfortunately, it’s a different feature.

  • Ismail K

    Hi jarrod i am your follower on youtube.

    i have msi delta 15 and i closed iGPU in bios. and laptop screen too closed.
    My laptop open on external display. i cannot enter bios because of is not mirroring to external display.

    i need factory rom of MSI delta for bios recovery/formating.
    How i can find it? Can you help me please?

    or
    can be backuping from a working msi delta 15 laptop with this app:

    Hi Jarrod,

    Thanks for the awesome content.

    I have a Zephyrus S17 with the 4K screen that you reviewed. I can’t seem to get the FPS boost when I attached an external monitor (Odyssey G7, QHD 240Hz). I plugged it into the USB-C that goes direct to the GPU. On the S17’s screen, I can get up to 90 FPS on Halo Infinite on Ultra, on the G7 I get 45 FPS on Low Settings. Do you have an idea what’s not working?

  • Ben

    Hi Jarrod, I wanted to know if there was any way at all to disable the igpu on the 2020 ryzen hp omen 15. I was considering 2021 legion 5s but they were a lot more expensive while the 2020 legion 5 did not support type c charging and was heavier than the omen, I also figured a 1660ti was enough for my use case, however at the same time I also play games like csgo where a mux switch would help a lot. I just wanted to know if there was anyway that does not involve an external monitor.

  • Andy

    Hi Jarrod, a big fan here!

    I want to replace my old gtx 1050 laptop to a newer more powerful one. I want a laptop that i can future proof it to keep it for at least 5-6 years without any problems. I was thinking to get an rtx 3080 machine with 16GB vram with at least qhd display (17″) as more and more games require more video memory. Do you think it’s a good plan to spend extra for a 3080 16GB?

    Also I was thinking about waiting for Intel’s Alder mobile CPUs as well for good performance as it showed the desktop version plus the efficiency cores for better battery life. Unfortunately I heard that the compatibility with some games of not pairing so well, resulting in poor performance or not even running. Would you recommend waiting for Alder lake expecting everything to work fluently or not? If not maybe Ryzen would be a better choice for performance and battery?

    Thanks!

    • Jarrod

      Unfortunately there’s no such thing as future proofing. Even if you spend big and get a top end model today it will likely be a bit of a struggle in modern games 6 years from now. You’d do better spending half the money today on a mid range option then spend the other half 3 years later on another mid range option. The 12th gen stuff will presumably announce at CES next week, so at this point might as well wait and see, unfortunately I cannot comment on performance at this time as I have not had the new stuff to compare just yet, but this should happen early next year.

  • Dan

    Hi Jarrod!

    Any chance that we’ll have more RX6800M laptops after CES 2022 form different manufacturers? If so, you think there will be a 17″ Lenovo legion version?

    Thank you!

  • sad guy

    hi.
    plzzzzzzzz help me
    i have a F15 FX 506 Li asus Tuf
    dont have graphic option in arrmor crate
    plz help me
    i guess i should buy a monitor

    • Jarrod

      I expect so, but I haven’t had a 3050 model to personally test and confirm, best bet is to Google search it I’m sure someone that owns it has shared their experience on Reddit or something.
