![]() In such a configuration, one cannot force a particular program that is not 'aware' of Optimus to use the dedicated card. It seems one would have to make specific enquiries to determine beforehand if a program is 'aware' of the Optimus system, or try it for yourself as an experiment. Most programs are not configured to make use of Optimus, an Nvidia system which controls the switch-over. Only the 3D settings are shown, the rest being hanled by the integrated graphics card.Ĭonclusion: Most programs will not make use of a dedicated graphics card where day-to-day graphics control is handled by integrated graphics. The Nvidia control panel in this dual configuration shows a limited set of options. GPU-Z (free) does show GPU activity on (both) cards, as was demonstrated when using the benchmark program above. How does one test a graphics card which is largely unused? Was described as an unreliable indicator - only certain programs might be shown here. Sure, you can select the Nvidia card, but unless the program has been written to use the Optimus system to trigger the switch-over, it won't. The right click option (on a shortcut or exe) which offers this: Even CUDA enabled video convertors (which are supposed to make use of the graphics card) will fail to do so unless they are 'aware' of the Optimus system. Most desktop programs will never use the Nvidia card. Instead an optimal choice appears to be 720p HD-class resolutions like 1280×720 and lower-mid detail settings. The switchover is only triggered by applications which have been specially programmed to make use of it - e.g. It requires better hardware resources than LoL and you won’t be able to play it on maximal settings and Full HD with the Intel HD 520. Some 90% of such laptops use this, and the whole arrangement is to save power and battery life. Switching software (Optimus) is provided by Nvidia to switch from the integrated graphics card to the Nvidia card. a conversation with the supplier tells me: They take very little time to set up as well.So. Configuring your eGPU with such wired and wireless options is easy. Other connectivity options include Bluetooth and VGA cable. If your laptop does not support such a hardware interface, you can try to go for an eGPU that supports USB-C.Īlso Read => Top USB-C Hubs for C-Type Devices Q #5) Can I use eGPU without Thunderbolt?Īnswer: It is not mandatory that you need to have Thunderbolt 3 input every time you use an eGPU. Since the eGPU comes with high graphic processors and PCIe support, it is expensive as well. The eGPU is designed to deliver the same graphics performance as a professional gaming laptop. Q #4) Why are eGPU enclosures so expensive?Īnswer: The cost of any eGPU solely depends on two factors- the compatibility mode and the performance it delivers. So installing the external graphics card for the laptop is not a problem. It can either be Bluetooth, VGA, or even Thunderbolt 3 port. Most laptops are now compatible with an external graphics card with the help of multiple ports. It allows you to get a powerful graphics display. It gets connected to your laptop by using a compatible hardware interface. Q #3) Can I install an external graphics card on my laptop?Īnswer: The external graphics card is manufactured to be working with your laptop. In short, yes- an external GPU is always worth it. It works quite similar to what every gaming laptop would offer. ![]() The external GPU provides the additional graphic support you need. You may not have the right specifications for every computer device that you are using. The eGPU will get the job done.Īnswer: The main objective of having an external GPU is to enhance the graphic performance of your PC or laptop. You may require watching 4K videos or playing games that require high graphics. However, it is an amazing device that helps to achieve desktop quality graphics on any compatible PC.Įxternal graphic cards do come with a compatible hardware interface that is easy to set up and use. Q #1) Can you have an external graphics card?Īnswer: The concept of having an external GPU or eGPU is relatively new in the market. You can also consider the price and pick an external GPU enclosure that fits your budget. Graphic support is one of the most important factors. Some devices also come with Bluetooth and VGA support. Even if you want to connect with a Laptop or a PC, you must have Thunderbolt 3 or USB-C compatibility. The hardware interface is another key factor to keep in mind. It’s better to pick up an eGPU that suits both Windows and Mac OS support. Pro-Tip: While picking up the best external graphics card, the first thing that you need to keep in mind is the compatibility of this graphic card.
