Preset that adds resolution and has lighting similar to AC II.
Wasn't going to upload this, but decided wt crap why not.
Not sure why, but screenshots look dark. Doesn't look like that in game.
If for whatever reason, the preset looks abnormally dark on your screen, just raise the brightness one level or two in your in game graphics options.
Unzip the file from the link below anywhere you'd like on your C: drive, preferrably in My Games, try avoiding Program Files of any sort as I believe I've heard that can cause problems with ReShade 2.0.
Once unzipped, run the ReShade Assassitant.exe as Administrator found within the folder.
Use a guide to install it for AC III properly like this one: https://www.youtube.com/watch?v=O65hjplP2mM
*Important* Make sure you use the right dll option for the Direct X version AC III uses. I believe it's the d3d9 option but I am unsure.
Once you have installed it, go to AC III SP in the ReShade Assistant manager, select "AC III AC II Style" option, then save.
Then go back to the window with all the preset options you were in before, click the + sign on top to add a new preset, name it whatever you want that you can remember what it is, enter that preset by double clicking on it, and save again.
Everything should work now, if not, post in the comments.
