uber pro tip: Having good displacement in a game needs a shitload of work to keep the quality high and consistent, which is hard for indie devs, even experienced ones. Also Acknex isn't famouse for it's fast rendering.
That's what I meant but I was too lazy to write everything down.
And by the way, pom with silhoulette correction is still faster, esp. for high frequency detail ;(
Edit: ...not trying to be offensive or anything. Oh and my grumpy attitude doesn't mean that I wouldn't be pleased to to see tesselation working in A8.
