That article tells it like it is. There weren't any games that required a specific feature level of 11 (to their knowledge), so its reasonable to expect the same for 12. When talking of feature levels, and even directx versions, keep in mind team leads and management have to see actual value in increasing the complexity of their work. Will utilizing a specific feature level of any directx version translate into more sales? Hell no in nearly all cases. These sorts of things will trickle in over years as the teams become more familiar with them, and their value is proven over time. How many of you have a team lead or a boss who's kinda sorta set in their ways? 😉
I say grab a 960 or the AMD equivalent, or whatever else you may want, and worry not.
