Resident Evil 4 game is much better than it looks and feels at the beginning. Console port looks ugly (GameCube version is the best) and controls are horror for PC gamers. Fans of previous games don't like it, as i know, because it's differ too much, like Silent Hill Homecoming vs previous, but for me Resident Evil is still good japanese game, i like it.
Modification developed to make PC version less ugly. More important changes for improving graphics can be done, but game is too old and not popular now.
You may see comparison screenshots from this mod and vanilla game in the gallery. Of course everything can be modified by yourself.
