Dedicated video card instead of integrated while running games

Hey Guys!

How to use dedicated video card instead of integrated for games? I have Intel i3 with integrated graphics and dedicated AMD GPU. Tried to find a way to do it but want to ask for your help.

Hi again @frowy,

Fair warning: I don’t have or use an AMD card or even an Intel GPU. This is entirely information gathered from the interwebz.

According to this site:
You can choose your discrete card for the applications who need it the most ( 3D modellers, games …) by prepending the DRI_PRIME=1 environment variable:

$ DRI_PRIME=1 *your_progam*

For example:

$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"

gives the output:

OpenGL renderer string: Gallium 0.4 on AMD TURKS

compare with

$ glxinfo | grep "OpenGL renderer" OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile

There’s probably much more to it, but that page’ll help. I think.

Hope it helps!
