Use an external monitor to potentially increase game FPS!
« on: May 11, 2020, 11:49:14 AM »

Connecting a gaming laptop to an external monitor does increase FPS in some instances and we will discuss why and how to properly set it up in this article. Most modern gaming laptops are using NVIDIA Optimus which makes use of the processors lower-powered integrated graphics to send the display signal to the laptop screen to improve battery life.

The discrete NVIDIA GPU usually sits idle when no GPU intensive tasks are running. But when you run a game, the NVIDIA discrete GPU will be used to render the frames.

In a gaming laptop that uses NVIDIA Optimus, the discrete GPU sends this output to the lower-powered integrated graphics which can result in a bottleneck and lower gaming performance, depending on the game and its graphical settings.

Most MSI Gaming laptops have the option to disable the lower-powered integrated graphics via software, or sometimes, it has a hardware switch that allows you to switch between integrated and discrete graphics like the MSI GT75 Titan.

One way to bypass the integrated graphics is by closing the laptop lid and using an external monitor, or by changing your display settings to only use the external monitor so that the IGPU will not be active while gaming.
We tested this Counter Strike: Global Offensive using an MSI GE75 Raider with a Core i7-9750H and NVIDIA RTX 2070 and the results are promising.

Comparing the performance on using the laptop screen vs an external screen (laptop screen disabled), we saw a 25% increase in FPS performance on CS:GO in 1080p high settings. While playing on the laptop screen, we got an average of 292 FPS while on the other hand, playing on the external monitor with the laptop lid closed gave us an average of 366 FPS.
You can try what works for you as results can vary with different MSI Gaming laptops, as well as with different games.  Hopefully, this quick article gave you an idea of how you can increase FPS with something as simple as using an external monitor.
