I'm curious, what was the most garbage specs device you tested the game on? Also did you carry forward any optimization lessons from league or were those not as applicable in a 3d FPS game?
We have this one laptop with an i3 and a Intel HD 3000. It's so old it had one of those mouse nubs. Always hate testing on that one. It's so old/slow it crashes our profiling tools. The screen is tiny too.
