INSTALLATION INSTRUCTIONS:https://reshade.me/downloads/ReShade_Setup_4.3.0.exe
First off download ReShade 4.3.0 from reshade.me and launch the exe to install to the game. Browse for FFVIII.exe in \Steam\steamapps\common\FINAL FANTASY VIII Remastered\
Choose OpenGL as the API, you can uncheck all the shaders unless you want to download them. YOU DO NEED to download at least one effect for it to load at all. I would recommend against having all of them installed because it would be a long load time.
After that's installed do not run the game yet. download one of these 3 files and unzip them into the game directory (\Steam\steamapps\common\FINAL FANTASY VIII Remastered\):
WIDTH ONLY RECOMMENDED
[attach]7251979[/attach]
For the 1920x1080 Width stretch only download this file:
If you have a different resolution you would have to edit BasicFx.cfg under steamapps\common\FINAL FANTASY VIII Remastered\reshade-shaders\Shaders\ReShade
The current magnify setting is only for 1920x1080, you'd have to figure out different Height and Width numbers for any other resolution.
