This is a SweetFX realistic preset for PES 2015. It makes the game realistic and with better graphics.
I like this even more than ps4. Easy to install. Unpack the file.
Copy and paste all files to the game directory – default Directory C://Program Files/KONAMI/Pro Evolution Soccer 2015 or C:\Games\Steam\SteamApps\common\Pro Evolution Soccer 2015
Start game and enjoy! If you have any problems try to import the preset into RadeonPro.
