Graphics Processing in Gaming Laptop computer systems
Most new betting laptop computer systems have 2 graphics processing contraptions (GPU) onboard. One is the cheapened-powered graphics cpu manufactured into the CPU scheme (also known as an iGPU or IGP). The 2nd is a high-powered AMD or NVIDIA GPU (sporadically referred to as a discrete GPU or dGPU).
The justification for the inclusion of both the iGPU and dGPU is convenience. As shortly as betting, the computer system carries out intake of the dGPU to surge the graphics processing. As shortly as obtaining utilise of a play dirty less demanding regimen, the product buttons to the iGPU for usefulness and much more detailed battery life.
Technologically, this form of configuration is labelled “iGPU passthrough”. Counting on the patient product and configuration you may also see something prefer hybrid graphics or switchable graphics. An additional replacement is Optimus innovation depending on your fitter, parts, and operating product.
In the rind of hybrid graphics installations, to maim the dGPU, the brandish needs to be literally fastened to the included graphics. The dGPU mostly runs in the background and sends information and images via the iGPU to the brandish. Sending those structures via the iGPU instead of unprejudiced to the brandish amasses 2 troubles. These are boosted latency and cheapened framerates. The nice news is, there is a much more detailed means to affix the brandish to the dGPU and avail switchable graphics, the MUX switch.
What Is a MUX Switch?
A MUX switch attaches the iGPU and dGPU to the laptop’s brandish in a opposite manner. This allows the dGPU to bypass the iGPU and send structures unprejudiced to the brandish.
A MUX switch allows to intake the iGPU and dGPU in switchable placement, depending on your needs at the time. A laptop doning a MUX is theoretically the pristine of both planets. You can intake your iGPU for best usefulness or the dGPU to avail the pristine thinkable usefulness.
So far, MUX buttons have been mostly applied by laptop OEMs prefer ASUS, Lenovo, and Alienware. Singularly opposite other constructors may start incorporating this utility into their givings.

NVIDIA and AMD’s Proprietary MUX Switch Options
AMD and NVIDIA each have their own technologies that diligent the specific same point via tantamount strategies. AMD’s Sensible Access Graphics Technology is comfortably available for its RX 6000-play dirty and more recent graphics, and NVIDIA’s Created Optimus is comfortably available for its RTX 30-play dirty and more recent objects.
The proprietary selections builded by AMD and NVIDIA distribution the specific same technologies to framerate and latency as a 3rd-party MUX switch, yet each comes doning cautions. AMD’s Sensible Access Graphics Technology is also lone comfortably available on laptop computer systems doning AMD APUs and Radeon GPUs, whereas a 3rd-party MUX switch is supplier-skeptic (definition it can be channelled out doning any kind of unification of AMD, Intel, or NVIDIA silicon).
Is the MUX Switch Much more detailed than Switchable Graphics?
As remarked previously, iGPU passthrough booms latency and suppresses framerates. Singularly, you’re not likely to alert a disorder in specification of latency, since the around 10% misusage in latency lone amounts to around 2 ms. Comparatively, whole product latency, i.e. the time it takes for the product to procedure a key-board or computer system mouse input and underline the expire result of that readjust on the brandish, is whole quantity overhead 30 ms, even on tools doning high-freshen-price display screens.
Affixing the brandish unprejudiced to the dGPU brunts framerates more substantially than it brunts latency, so this is wherein obtaining utilise of a MUX switch to bypass the iGPU has the a play dirty of advantage. On mechanisms doning a MUX switch, readjusting from the iGPU passthrough to the dGPU unprejudiced rapport whole quantity expire outcomes in a framerate surge of 10-20%.

Are There Bad facets to a MUX Switch?
Imparted that a MUX switch allows procedure of the graphics in both hybrid and unprejudiced rapport installations, there are couple of bad facets. Using switchable graphics incapacitated via the MUX switch, the laptop harnesses its fullest usefulness at the price of battery life and usefulness. As shortly as switchable graphics are enabled, the laptop can dynamically switch between iGPU graphics and dGPU graphics, permitting for much more detailed usefulness.
One oddity on some mechanisms is the loss of features when diluting hybrid graphics – for example, our Lenovo Legion 5 lessens FreeSync (a innovation that takes care of the freshen price of a fastened supervise) encouragement when hybrid graphics are incapacitated.
Some Features May Go Missing
Using switchable graphics enabled, the Radeon Software brandish positions internet page proves a toggle to enable FreeSync.
Taking advantage of the specific same laptop, doning the NVIDIA GPU regulating the brandish, there is no replacement for variable freshen price replacement in the sidebar wherein it need to be.
An additional anomaly of MUX-switch-outfitted laptop computer systems is that in act to gain the switch, you need to restart the laptop. NVIDIA’s Created Optimus carries out not have this hindrance and can switch between switchable graphics to dGPU-lone placement on the fly.
In the rind of an NVIDIA dGPU doning a 3rd-party MUX switch, brandish recording doning ShadowPlay is lone thinkable if the NVIDIA GPU is processing the brandish explanations, definition lone in stabilized video games, or when rushing in dGPU-lone placement. To document the desktop, you will clearly need to restart the laptop if it’s not already in dGPU-lone placement.
Some laptop computer systems, prefer the Alienware m15 R5, gain you obtain in the BIOS. There you can switch between dGPU-lone and switchable graphics positions. Acquiring in BIOS encompasses added altercation to the procedure and potentially hides the utility from a play dirty less blossomed individuals.
Lenovo’s Vantage software for its Legion laptop computer systems allows you to switch graphics in Windows, yet proves you a ultimatum that you need to restart to apply the readjust.
Who Need to Buy a Laptop Using a MUX Switch?
MUX buttons are instead a play dirty lone fruitful in betting executions. Switchable graphics will clearly not affect the usefulness in veteran workflows, prefer GPU velocity of video and 3D carries out. The lone humans that need to be pertained to around a MUX switch are gamers. Yet not even unanimously gamers need to be pertained to.
What Galleries Well worth the Most From a MUX Switch?
A MUX switch substantially clouts video games that placed a play dirty of strains on the CPU doning high framerates.
Titles prefer CS:GO, League of Tales, Paladins, Call of Obligation, Battleground V, and DOTA 2 rushing at or below 1080p will clearly see the greatest breakthrough. GPU-banned sightseeing and tour video games, prefer Manipulate, Assassin’s Tenet Valhalla, and The Witcher 3 will clearly see a play dirty less dramatic technologies, particularly at better resolutions. Some video games also simply worn’t last offer high FPS.
In RTS video games prefer Anno 1800 and Period of Realms IV, for example, a 15% FPS bump would clearly be of miniscule advantage, since framerate doesn’t affect gameplay too substantially. The specific same can be said for the previously mentioned sightseeing and tour video games.
Further, if you mostly arcade on an exterior supervise, you also shouldn’t qualm around a MUX switch. HDMI and DisplayPort miens on laptop computer systems mostly affix unprejudiced to the dGPU, obliterating the iGPU bottleneck.

Weigh If the Deportment Links Uninfluenced to dGPU
If you cramp to reflect whether the spoof attaches unprejudiced to the dGPU on a laptop in a store front front or one you already have, you can check this in the NVIDIA match panel:
- Open the “NVIDIA Manipulate Panel” by right-clicking on the desktop and deciding the replacement from there.
- Alternatively, you can open the play dirty by right-clicking on the “NVIDIA Manipulate Panel” icon in the Windows product tray. Establish the replacement from there.
- In the “NVIDIA Manipulate Panel’s” disowned sustenance selection pane, attend “3D Stances”.
- Click on “Configure Surround and PhysX”.
- On the right, you need to currently see a diagram that connotes which GPU the brandish is fastened to. Weigh the environment-friendly box in the envision marked “Laptop Sport”. This connotes that the brandish is currently fastened to the AMD Radeon Incorporated Graphics.
You can also comfortably check which graphics cpu is currently regulating your brandish obtaining utilise of AMD’s Radeon Software:
- Open “Radeon Stances” from the Overture Food selection. Or, if you can’t see it, comb for it obtaining utilise of the pub at the peak.
- On the “Radeon Software” internet page, attend “Stances” by clicking on the Creation-sculpted icon in the upper right side.
- Establish the “Sport” tab.
- On the brandish positions internet page, check for “International Sport” at the peak.
- Listed below you can see if the brandish is fastened to the included graphics or to the discrete NVIDIA graphics.

How Undertake I Weigh If My Laptop has a MUX Switch?
There is no one-dimension-suits-unanimously means to check if a laptop has a MUX switch — constructors worn’t whole quantity unprejudiced list it in the specification sheet of the objects, and Windows doesn’t mostly list it in the machine manager. So, how can we check for the visibility of a MUX switch? Most betting laptop computer systems have some filter of betting software play dirty – ASUS has Armoury Pet crate, Lenovo has Lenovo Vantage, and so on. These either comes pre-mounted or can be downloaded and install from the fitter’s website, and you can intake these transferred out match clinics to check whether your machine has a MUX switch.
To check whether your laptop has a MUX switch, open the match nucleus software and diligent aesthetic prestiges for an replacement to maim hybrid graphics (sporadically also labelled MSHybrid or NVIDIA Optimus) or enable the transferred out GPU placement (also labelled Unconventional Stashing). These selections may be buried in a graphics configuration or betting sub-sustenance selection, so it may steal some digging deep into.
If you worn’t see an replacement to maim the hybrid graphics or enable the dGPU placement in the software play dirty, you can check in the machine’s UEFI or BIOS if there is any kind of pointer of switchable graphics, hybrid graphics, or discrete graphics placement. It is not widespread for laptop constructors to bury the MUX switch configuration selections in the BIOS. Virtually unanimously laptop computer systems doning a MUX have schedule to the selections via software, yet Dell and Alienware betting laptop computer systems are 2 excellent exemptions to this, since they do conceal the MUX switch selections in the BIOS sustenance smorgasbords.
As a last hideaway, you can check Reddit, or the fitter’s encouragement internet page to see if any guy else has possessed a tantamount woe. Multiple brands prefer Dell, Eluktronics, and Lenovo have agents that proactively rebuttal disorders on discussion forums prefer r/GamingLaptops, r/dell, r/eluktronics, and r/lenovo.
Laptop computer systems Using the MUX Switch
ASUS has decided that unanimously of its laptop computer systems in 2022 and past are designed doning either a MUX switch, Created Optimus, or Sensible Access Graphics. Most of Lenovo’s Legion lineup and innumerable MSI and Eluktronics laptop computer systems also utility MUX buttons – can you tell the MUX switch came to be rather of a pattern in 2021?
Nanoreview preserves a extensive list of betting laptop computer systems doning MUX buttons, so if you’re purchasing around for a betting laptop and think you may advantage from a MUX switch, it’s worth frisking if the selections within your wallet are on the list.

Intermittently Quized Questions
Will I alert the heightened usefulness when obtaining utilise of a MUX switch?
It trust funds your laptop configuration and your intake rind. If you’re obtaining utilise of a laptop doning a 1080p high-freshen-price brandish, a high-expire GPU, and you’re playing video games that supply framerates overhead ~100 FPS, indeed you will clearly alert. If you’re obtaining utilise of a 60Hz panel, or you’re already obtaining utilise of cheapened-expire equipment, you conceivably won’t alert a disorder. Further, if you are purchasing a betting laptop as a filter of cheapened-price workstation, you last offer not qualm too a play dirty around a MUX switch, since productivity executions worn’t advantage from a MUX switch.
Can you place a MUX switch after you’ve received your laptop?
However, you cannot have a MUX switch as an aftermarket element. As doning a play dirty of core laptop parts, a MUX switch is something that needs to be included into the design of the motherboard and applied during the production procedure. Further, constructors need to match both the firmware and software of the machine to accommodate the MUX switch. If you are peeking for the specific same usefulness surge that a MUX switch transactions, your pristine wager is attaching an exterior brandish to your laptop via an HDMI spoof or DisplayPort, as that whole quantity bypasses the iGPU.
Is it a offer-breaker if a laptop carries out not have a MUX switch?
Not at unanimously. In some skins, thermal design can tinker a bigger obligation in laptop usefulness than any kind of MUX switch can. If you are comparing a laptop doning a MUX switch and an RTX 3050 to a laptop doning an RTX 3060 sans MUX switch, you’re much more detailed off going doning the model doning the more efficient graphics in the RTX 3060. There’s more to a betting laptop than a MUX switch.
