Well that's nice, not all of us are fanboys. There's already been gameworks titles found with irrationally excessive use of tessalation (to the point where its 10x what is needed with near zero visual improvement for all the excess). i.e. rendering tessellated water under indoor levels....just because. You have to be pretty naive to think that these are unintentional decisions- they will gimp their own performance for 3-5% with no visual improvement if it means it gimps their competitor's cards 10-15%.
That said, AMD should take responsibility for how they handle this in their own drivers.
