My desktop shreds it on Ultra with lowish load. The lightning shows me in color the load (green = low, blue = 50%, Red = 80%+) and it rarely goes blue. Also its cold and i can tell its having an easy time. The laptop on the other hand, doesn't even matter the settings i use (windowed mode on low ffs). Its just a hot mess and runs like crap.
