I have read from many places that DirectX 11 should add some features and improve performance of even current DirectX 10 cards. Newer cards benefit more from new features but it doesn't mean older cards can't benefit some too. At least MS have said that they have improved multicore CPU usage (yes, CPU not GPU) with DirectX 11 which might explain better results in many cases. After all DirectX is overall gaming API, it's not just about GPU. |
That was said about DX10.1 but the only cards that got performance improvements were AMD's actual DX10.1 cards. Nvidia, who doesn't have any retail DX10.1 cards did not recieve a performance boost in games that were patched for it (e.g. Assassins' Creed was patched to remove DX10.1, which decreased AMD performance).
