As of late most laptops come with an integrated graphics processor built into the CPU to save power when performance is not needed and a separate discrete graphics card (be it NVIDIA or AMD) that is meant to be used by more demanding 3d applications.
While mir chronicles is not exactly a very demanding 3d application, it actually makes the integrated graphics card look like it comes from the 90's. If I run mir on any of the latest notebooks and the game runs off the integrated graphics card, frames per second go all the way down to 40/30 once there is some action, or even sitting in bichon wall, which automatically makes everyone else that is running mir at 60fps 2x faster.
Both amd and nvidia give the opportunity in their respective control panels to force so or so application to use the external graphics card. This works for about every game and application under the sun, be it from 1994 or 2014. All but mir chronicles. The game runs off the integrated and doesn't give a crap what the user sets it to.
This was tested and replicated on 3 different tier HP notebooks, 3 different tier Asus notebooks, 1 Alienware notebook and 1 Acer notebook, all of which either had NVIDIA or AMD/ATI external graphics.
Only one of the systems was able to run mir off the external graphics card, and it did so merely because the integrated graphics card could be DISABLED in the notebooks BIOS, so that only the external would be switched on in the system. It was the only system where such thing was allowed. It was one of the HP notebooks by the way.
It seems like mir runs off whatever the operating system is running off, disregarding what is set in the nvidia/amd control panel.
Can this be addressed in some way, devs?

For part of my Degree I needed to port an old DX5 game engine to be DX9 (the latest at the time) compliant, without usinf deprecated classes. It took me many many hours before I stopped trying to alter current code - and just coded an entirely new rendering library, and replaced any calls to that.
