Most of the time, a person labels a game as "unoptimized" whenever their computer can't play it maxed out. People expect every new game to run flawlessly on their hardware, even mid-range hardware. And if it doesn't, the game gets labled as "unoptimized". What they fail to realize is that lowering the settings in the game will give you just as playable results, that look just as good or better than some of the other games which they say are "optimized". GTA:VI and Crysis are two examples. On max settings, both games struggle to run on even high end hardware. However, lowering the settings, even just to high in Crysis, give an enjoyable experience that runs fine on mid-range hardware. People often say crap like "Well HL2 runs great maxed out on mid-range hardware, so crysis should too, that is why Crysis is unoptimized". The problem with that statement is that HL2 maxed out looks like ass compared to Crysis maxed out. Crysis on medium looks better than HL2 maxed out.
