The anti aliasing section offers two alternatives to what is offered in game. The entry for SMAA via SweetFX links to a custom SweetFX download. Instructions says to "replace DLL's with ones from "x64" folder" after extracting contents of archive, but there is no x64 folder in the archive. Game simply doesn't start without it.
The second entry for SMAA via ReShade links to a DMCA'd mediafire link.
