league of legends runs better with apu graphics rather than rx 460?



By plainly looking at the fps

rx 460: 40-60 fps in game
apu- 60-100 fps
 


Is it not a bottleneck? And yeah installed the latest drivers for sure man
 


Of course, I'm completely dumbfounded. The rx 460 is also being used for sure as the Dvi is plugged into the gpu port
