Batman makes it three for three as far as failed patches go for the current major releases.  Battlefield’s patch was probably the best of the three, Skyrim being the worst with Batman’s simply failing to deliver what it promised … improved DX11 performance.  [H]ard|OCP recently reviewed the original game and now has published the results of their testing with the new patch.  The good news is that most of the stuttering and crashes have been fixed, leaving only significantly lower performance when in DX11 mode compared to DX9.  Originally you could expect a 50% reduction in fps when enabling DX11 and NVIDIA users can expect the same results at this point, AMD users will see their performance reduced by even more than pre-patch though the game its self should be more stable.  If you want to run Batman Arkham Asylum at high resolution, you better have two GPUs.

"Days after our Batman: Arkham City Gameplay Performance and IQ review was published, the game was patched. The patch was ostensibly reported to fix DirectX 11 performance problems plaguing the game, but does it really do the trick? Where do our DX11 video cards stand now?"
