An interesting queston for you.
OK so get ready for a doozy. I have a MacBook PRO with a windows 10 partition. The Mac side of things, as far as league is concerned play beautifully. On windows, (even when I had 8.1) the launcher would be smaller due to the high dpi settings but would run fine but the actual game portion of league (they are not the same) would have fine detail and quality but the health bars above things would be tiny and the numbers for everything would be huge as well as my name. Because I find myself on the windows side of things more regularly due to other games with friends, it becomes very frustrating to have to switch over to MAC to play league. If anyone has any advice I would love to hear it. I have tried to run the compatibility trouble shooter for the game itself and I was told by my computer that I couldn't access the game that way and that I had to go through the launcher to test the program (effectively telling me that I couldn't test or troubleshoot the program)
