We've struggled with justifying raising the min spec for our game over the last decade and recently pushed up to 4.2 as well. Historically the question was always one of which optimizations we would be able to 'compile in' (rather than detect and use if available) and it has been increasingly difficult to justify in recent years: a few ops in 4.1, one op in 4.2, but nothing dramatic and we still can't rely on F16C support yet. These days, the move to exclude older processors seems more designed to avoid headaches from failing older hardware and performance complaints from systems that might technically qualify for your minimum spec but can't offer a satisfying user experience than it has to do with the software being able to take advantage of instruction set extensions.
