I agree but it's a balancing act and depends on the game. For Overwatch I turn off/down a couple of key settings to boost FPS significantly. For an RPG, I leave it at max settings and suffer the occassional drops to 50-60 FPS.Settings are there to be tweaked. Max settings are not a Holy Grail. I prefer to trade a bit of image quality to get smooth framerates. But thats me.
I was referring to future with Volta it will probably be simpler to keep steady 144. For RX480 freesync is definitely the way to go
