Recently I've been dabbing my hands on the European PC version of Silent Hill 2: Director's with sh2proxy so I can run this game on Windows 8.1. The page claims that the game doesn't support anisotropic filter but I've messed around with the video card settings for this game by forcing x16 anitropic filtering with x8 anti-aliasing and it looks much better than just the anti-aliasing alone. I'm not sure if sh2proxy has anything to do with that since it is meant to fix the anti-aliasing support for the game and I don't know if it'll work for the Modern Compatibility Fix for the U.S. version.

If it works for you, then I guess you may just put "hackable" in that field and mention the graphics card control panel
