At first, I thought that my GPU was failing because I have it working with a SATA adapter to 6 pins power. The failure consisted in opening blender and run some file moderately complex graphics and Cemu in Zelda when I took the viewer, the pc was froze.
I decided to install Optimizus Manager since I have 2 monitors and through Corectrl I see that the use of the pc is static as if it was not being used. However, when using Cemu and play if you use the GPU, the use of the pc is static if you use the GPU.

Removed useless screenshots
Hello @liltingle 
What do you expect? There is the Intel GPU which is used by default and ab Amd GPU which can be used on demand. When you start blender without targeting the AMD, it will use Intel.
well thatβs what you would expect to happen, it just never happens, it only happens in the cemu emulator that gives you the option to specify which graphic to use.
Moderator edit: Useless images removed. Again.
What is your main gpu now? Where is what connected? Which GLX are you using by default? You provide zero information about that. See what @cscs linked plus:
glxinfo | grep "OpenGL renderer"
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
What cemu emulator actually does is switching GLX. It applies DRI_PRIME=1 before launching emulation, which is what I call βused on demandβ.
Or use xrandr (if you use xorg, not wayland) to set the βrender offload sinkβ, see here: PRIME - ArchWiki

So you understand now what I mean? It does not switch automatically βOpenGLβ β βGLXβ.

ooo great using DRI_PRIME=1 before running blender I get the expected result, to transpolate that function to the whole system I have to use which command?
xrandr.
xrandr --listproviders
xrandr --setprovideroffloadsink radeon Intel
xrandr --setprovideroffloadsink 1 0
More information see man xrandr
$ DRI_PRIME=pci-0000_06_00_0 glxinfo | grep 'OpenGL renderer'
Providers: number : 2
Provider 0: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 5 associated providers: 1 name:modesetting
Provider 1: id: 0x87 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 1 name:modesetting
$ xrandr --setprovideroffloadsink radeon Intel`
Could not find provider with name radeon
$ xrandr --setprovideroffloadsink 1 0

Please read the link I provided:
There is also an example for a xorg config mentioned for a permanent solution.
what I donβt understand is why xrandr --listproviders gives me 2 modesetting, instead of 1 amd and 1 intel.
Because both are running with xorg modesetting (Kernel Mode Setting) driver, which is the default nowadays. Yeah I understand, it can be confusing, but early there were actually 2 different drivers.
yes, but I think there is something not specified or wrong with my pc configuration.
xrandr --listactivemonitors ξ² 
Monitors: 2
0: +*VGA-1 1366/413x768/234+1366+0 VGA-1
1: +HDMI-1-3 1366/410x768/230+0+0 HDMI-1-3
as I understood this command is to invert the order but as the option of the names is discarded because they are the same, the numbers could be an alternative however it gives this error
xrandr --setprovideroffloadsink 0 1
