If you are from old school Arch Linux you might remember me as a former Arch Developer. The thing is I took a long hiatus from Linux since work life gave me no time to get involved with the community. But now I have returned!
So the thing is my Laptop a Lenovo y40-80 like almost all laptops have integrated graphics provided by Intel and also a Powerful AMD R9 275M. Try as much as I can I can not get the AMD to run applications or games it uses the integrated one, and I have done everything in the wiki and forums.
I installed the xf86-ati instead of the amdgpu one because I think my card goes with that driver.
glxinfo | grep "OpenGL renderer" OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2)

When I launch the game with DRI_PRIME=1 it doesn't make any difference. Tell me what info you need to be able to help me.

That looks fine, how do you know applications or games aren't using the AMD card?
Well, that's one of the things I don't know, I just assume because of the crappy performance, but maybe the open source AMD drivers are still that bad. I would like to find a way to know which graphics card is being used at which moment.
Well, you could install radeontop, use that to monitor your dGPU. You should see a difference in utilization.
Other than that: CAPE VERDE is not exactly the latest and greatest from AMD, I should now, I have one of those myself...
OK, solved. Did a complete reinstall this time went comoletely cutting edge. I was ext4, xorf, kde. Now I went btrfs, wayland, gnome. And did the exact same open source amd drivers configuration and wow, the game runs perfect now at full settings!
