How to toggle the MUX Switch in Armoury Crate But in a competitive game where every millisecond counts, you can enable a discrete GPU mode in Armoury Crate to get the best gaming performance possible.

That way, when battery life is crucial, your machine will act accordingly. This microchip allows the dedicated GPU to bypass the CPU and push its frames directly to the display, reducing latency and boosting framerates by an average of 9% in our testing-though some games, like Rainbow Six Siege, saw more than a 30% boost. We first added MUX switches to our flagship laptops in 2018, but in 2022, we brought them to the entire lineup.

You’ll still get great performance, but you won’t be able to push that graphics chip to its absolute max. There’s a minor downside to this approach, though: since everything has to pass through the CPU, the GPU isn’t able to give 100% of its horsepower to those intense gaming sessions. After all, if you’re only performing low-power tasks, why let your GPU draw power it doesn’t need? This has a few advantages, primarily in the realm of power usage: by communicating with each other in this way, your laptop can turn the dedicated graphics on and off as needed, which can more than double your battery life. Typically, your laptop’s dedicated GPU will render the frame, then route it through your CPU’s integrated graphics before sending it to the display.

Modern gaming laptops work a bit differently. This provides low latency with little performance overhead, giving you that split-second chance to see your enemies before they see you. When the GPU finishes rendering a frame, it sends it straight to your screen-where it’ll appear right away (provided you’re using a G-SYNC or FreeSync-capable display).
ASUS ROG X13 PC
On a desktop PC with dedicated graphics, your monitor is hooked up directly to the graphics card. Starting in 2022, we've expanded our entire laptop lineup to include a MUX switch. Every time we build a laptop, we tirelessly re-configure and re-test prototype machines to maximize performance from the CPU and GPU, and now we’ve added a new hardware component to help take performance even further. In a frenetic firefight, a few frames can mean the difference between triumph and defeat.
