Follow this link and follow the rules for installing new filters into your settings. I had to leave my game once I had installed them and opened it back up and they were there. The link for the download is in the paragraph highlighted green saying "download". I've included my settings and it is crazy how much better it makes this game look and helps.
If anyone needs some help just comment and I'll do my best to help.
Edit: By request here's a side by side comparison from before/after.
