Over use of tessalation=Crysis 2, Batmans cape, COD wolfs and the dog.
We have 2 Nvidia employees stating the polar opposite, one states AMD have access to game code and the other stating AMD don't have access to game code as they are a competitor.
Hairworks is valid in line with GW performance.
I'm using Nvidia and AMD, and never saw any issue in WD's so far and have stated so a few times already, COD, I don't have, but I have BAO and the performance delta is way, way off until you add MSAA which is a brute force approach at a driver level.
Asking a silly question, do you mean source game code or do you mean source gameworks code as they are really two different things, and which was the nvida Employee talking about talking about?
