To the best of my knowledge, the game has advanced so far that these Plugins are no longer necessary, and the obsolete textures they provide can take up excessive in-game memory
But you can try them if you wish
Just extract the files you want using 7-Zip, and drop the resultant PlugIns into your STALKERSOUP game folder
Ideally, test them one at a time, making a note of its name so you can uninstall it again by removing the file
NOTE: Some of the packs have choices I.e. Shiny asphalt OR High-Res asphalt, 16:9 OR 16:10 aspect ratio, so make your choice. Not both!
BTW Where did you get the Resident Evil plugin, please, as I've not seen that before?
