Radeon-R7-M445, laptop, hybrid: Intel-HD-620

[MS]

What is interesting though, is that once you set the global environmental setup of DRI_PRIME=1 and then make XORG configuration file including enabled option of TearFree, the system will set your OpenGL display driver and device for the Intel, instead of the Radeon, nonetheless by performance difference - for the better - one can tell there is indeed some extra V-RAM buffer going on in the background, cooperating with Intel. It may suggest that somehow this way the Intel hijacks the OpenGL, but in the end, everything works on enough acceptable level, albeit drivers could be better. On the other hand, are hybrid graphics not supposed to work in such a manner?
