.ini file tweaks to ramp up performance?

[QED20]

Any clever .ini file tweaks for this game? I heard that turning of DOF is a performance boost but I'd rather not sacrifice that for ~5 frames.

Some ini tweaks I found online

''Some nice Batman tweaks, from 'bmengine.ini' located in this folder >> Documents\WB Games\Batman Arkham City\BmGame\Config, set the .ini file to read only after tweak so it can't be reset.

[Engine.Engine]
PhysXGpuHeapSize=128 <<<boosted x2
PhysXMeshCacheSize=16 <<<boosted x2

bSmoothFrameRate=FALSE <<disabled (seems quite important)



[SystemSettings]
DepthOfField=False
OneFrameThreadLag=False''

''I found this on the arkham city forum. It gave me smoother frame rates and less stuttering.

Your config can be found in My Documents\WB Games\Batman Arkham City\BmGame\Config and it is the UserEngine.ini

Note: The Tessellation tweaks do not work because Tess needs DX11.''

Make sure you do a backup before you modify the ini file.
