Comparing DirectX 9 to DirectX 11 on the pc release of Batman Arkham City.
There's not a lot of difference between dx9 and dx11 ingame, and not enough to warrant the poor performance on dx11
Take note of a few things..
PhysX was running on both tests
The benchmark was done while recording with video capturing software (not a separate PVR etc) and also onto the same hard drive as the game was being played from, so the fps displayed isn't a true reflection of ingame fps when not recording, but it gives you a rough idea what to expect pre-patching.
The DirectX 11 version of the game has widely known performance issues across different setups. For me its plays ok, but with sudden fps drops and freezing (as you see on the DX11 recording). Playing on DirectX 9 is fine with no issues at all.
Rocksteady are aware and advise this game to be played on DX9, which seems stupid as the game was "delayed" to give the pc advanced features that DX11 brings, like tessellation, Deeper graphics and what appears to be a new DX11 feature.. "dont use dx11 use dx9"
