Using nVidia inspector you can enable 8x Sparse Grid Super Sampling.

Force SGSSAA (Nvidia only)

Download and run Nvidia Profile Inspector.
Search for Bionic Commando in the profiles list.
Set Antialiasing compatibility to 0x004010C1.
Set Antialiasing - Mode to Override any application setting.
Set Antialiasing - Setting to 2x/4x/8xQ Multisampling.
Set Antialiasing - Transparency supersampling to 2x/4x/8x Sparse Grid Supersampling (the level must match the previous setting).
Optionally, set Texture filtering - LOD Bias to either -0.500 (if using 2x MSAA + 2x SGSSAA), -1.000 (if using 4x) or -1.500 (if using 8x). This will increase sharpness, but may mess up some visual effects.
