AMD TressFX was literally unplayable on 680gtx until Nvidia optimized it on their own you had framedrops to 15fps, 680gtx /highend/ was slower than 7870 /mid tier card/

Do I need to address your other tales or was that enough for you ?
Do I have to remind you first AMD DX11 games, like Dragon Age II where 580gtx was slower than piss poor AMD 5770HD, which is even slower than the oldy GTX260 at FullHD?
DX11 is pretty much optimized and runs better than DX9 and DX10, it is AMD fault their driver has serious overhead issues under DX11.
As always, AMD is never to blame, it is always the others.
Because TressFX was OPEN, it took Nvidia LESS THAN A WEAK TO OPTIMIZE.
Any more lies, hoping that no one remembers?
The rest of your arguments are not any better. For example, AMD had driver problems because all games where developed on Nvidia hardware. A couple of years after the introduction of the new consoles and before AMD started losing market share again, we where seeing a number of problems with Nvidia drivers in games. That was normal considering that developers where creating games primary for the console hardware that was ALL AMD. Nvidia's programmers didn't forgot how to program drivers all of the sudden. The games where made with AMD hardware in mind.
