Did everything as instructed, however when I launch the game (through SKSE) I get an error message "could not load RDR2Upscaler.org" and when pressing ok the game closes. The RDR2Upscaler.org is sitting in the mods folder, created from the upscaler .dll with Symlink, however it has a size of 0kb. which seems weird.
RDR2Upscaler.org has to be in the Skyrim game folder where is the exe is. Do not forget download the Launcher! The RDR2Upscaler.org is a crack anyway, because Pureshit mod needs auth.
1. Launcher files - drop everything in the Skyrim folder
2. In MO2 or Vortex make a "new mod", open it and place the upscaler files: SKSE and UpscalerPlugin folders, activate it
3. Ho to the Sykrim folder has to be a mods folder, already contains the Symlinker (you can run through on MO2, Vortex or normal that will create a symlink as SkyrtimUpscalerplugin.dll - rename it to RDR2Upscaler.org)
4. copy the RDR2Upscaler.org (crack, workaround) and place the main Skyrim foder
