I think SweetFX does that too...Didn't test it on this game but SweetFX does it's job pretty good.EDIT:I don't know why but SweetFX doesn't work for this game (at least not for the Demo [Idk why my original game won't launch]).
All, that postprocessing, oh god...I don't like it... :\
crazzy mentioned SweetFX. You might wanna give it a try: http://www.guru3d.com/files_details/sweetfx_shader_suite_download.htmlIt should be possible to sharpen the graphics using SweetFX, haven't tried it myself though...
