I've just installed Batman and the graphics performance is... well, not too hot.
Can anyone recommend which settings will give me the best balance between quality and performance? I have 2 MSI Geforce N560GTX Twin Frozr II graphics cards in SLI.

Below is the settings for the game.
For all other games I always just set it to the highest quality and enable all features. This is a first time for this pc. I've already reduced Anti Aliasing, DirectX 11 Tessellation (whatever that is) and Detail Level as below.


Hardware Accelerated PhysX is set to Normal.

Also, I'm not sure if I should leave my graphics settings in SLI or should I dedicate one of them to PhysX. I really don't know much about this stuff, so any recommendations would be welcome. Below is my SLI settings.
