   - It lowers performance. Since the dGPU is giving frames to the iGPU and that passes it to your monitor, performance can suffer, sometimes up to 20%.

 ==== What is a MUX Switch ==== ==== What is a MUX Switch ====
 MUX switch allows switching off the iGPU, but you need to restart the device. When the iGPU is off, the display output won’t be routed through the iGPU, so there will be no performance hit, and no RAM will be reserved for the iGPU. This isn't Nvidia exclusive as Lenovo showed on their all AMD RX6000 Legion MUX switch allows switching off the iGPU, but you need to restart the device.

   * In practice, the solution tends to be a bit buggy, which is why many users still prefer the solution with MUX switch, even though it requires a restart to switch between “best battery life” and “best gaming performance” options. \\   * In practice, the solution tends to be a bit buggy, which is why many users still prefer the solution with MUX switch, even though it requires a restart to switch between “best battery life” and “best gaming performance” options. \\
   * Also on some laptops there is no way to fully disable Optimus or Advanced Optimus, so not having it can be a bonus to some users.   * Also on some laptops there is no way to fully disable Optimus or Advanced Optimus, so not having it can be a bonus to some users.

 +==== How do I know if I have Optimus enabled or disabled ====
 +Disconnect any external monitors and open Nvidia Control Panel (the old, Windows XP looking one). \\
 +If the only section there is "3D Settings" then you have Optimus enabled.
 +
 +==== How do I know which outputs use dGPU and iGPU  ====
 +In Nvidia Control Panel, look for "Configure Surround, PhysX". There will be a diagram showing you what ports are wired to what. If you only see one GPU, your dGPU, you have Optimus disabled.
 +
 +==== How do I disable Optimus ====
 +Assuming your laptop allows it, it will be either in your OEM's control panel or in your laptop's UEFI settings. There is no native Windows toggle.
