Yes, I realized that the moment I hit submit. On topic: Skyrim could benefit a ton from tesselation on all those trees, bushes, flowers, etc. Yet, they didn't because as long as it is playable, people just don't care. The only benefit, really, is higher average FPS. It boils down to a simple question: is it worth fundamentally changing the engine to support Direct3D 10/10.1/11 features or are we okay with what we can do without? Answer is always the latter unless you commoditize the engine (like Epic and id software).
