A job that Capcom should have been able to do originally. Basically, Albert found out how to cut and paste the textures from the Gamecube version to the PC version with much ease. This mod made massive progress so quickly, because of the simplicity behind it.
Resident Evil 4 Texture Patch v2.0, by Albert Well here are the essential mods I've found that improve the visuals without making drastic changes. Also, all the cutscenes were pre-rendered, instead of realtime like Gamecube offered, which meant they had compression artifacts and your unlocked costumes were never shown.
Namely, polygon counts and textures were cut in half, and a lot of the environments were trimmed down in subtle ways, and various other effects were either removed or downgraded. For those who don't know, the PC version was a port of the PS2 version, which was extremely flawed compared to the Gamecube version. I decided to revisit RE4 on PC and see how far the fan-base has been able to enhance the visuals.
