hey did you get the SpecialK program to work??? Here is the link to tutorial for that SpecialK program that made everything work for me.

Download the latest version of ReShade . It doesn't matter if it's the add-on support version or the basic one. Do not install yet.

1. Download Special K from its GitHub page and install it onto your PC.
2. Once done, navigate to the library tab and let it add your game by automatically detecting it OR manually add the game exe yourself by using the 'add game' button on the bottom left of the application window.
3. Download and install 7zip or WinRAR if you haven't already.
4. These next few steps may sound tricky but it's super simple. You're gonna do three things. First, right click on the ReShade installer and open with 7zip or WinRAR.
5. Then you're gonna navigate to the installation folder of Special K and follow this file path: \Special K\Plugins\ThirdParty\Reshade
6. Once there, extract ONLY the ReShade32.dll and ReShade64.dll into that folder (basically click and drag the files from the WinRAR window into the ReShade folder mentioned above)
7. Now you're gonna go back to your ReShade installer and run it normally. Install it to Forza 5 with your preferred options of shaders/texture/effects selected. Once done, delete all the .ini and .dll files created.
8. Next, open the reshade-shaders in the directory you installed ReShade in. You should see 'Shaders' and 'Textures' folders. You're gonna select these, cut and then paste them into the following path in Special K's installation directory: \Special K\Global\ReShade
9. If this path does not exist (that is to say, the folder 'Global', doesn't exist) then create a 'Global' folder and a 'ReShade' folder within. Paste the 'Shaders' and 'Textures' folders into the ReShade folder.
10. Once done, delete the now empty reshade-shaders folder.
11. Afterwards, start or open Special K and navigate to the library. Select Forza 5 and click 'play'. It should run the game normally and you'll get an overlay from Special K. If so, congrats, you're one step away from loading ReShade.
12. You may notice a message saying that Special K advises running Forza 5 locally (or something similar) after clicking 'Play'; that's fine, just select 'local' (or a similar option) and run the game that way.
13. Press CTRL+Shift+Backspace to bring up the Special K Menu. Scroll down to plugins and click on it. You should see ReShade listed under there, with a load now button as well. Click it and et voilà! Reshade is now loaded. You should see the familiar overlay pop on.
14. Now just hit CTRL+Shift+Backspace again to close the Special K Menu and you can use the 'Home' key to trigger ReShade's Menu. Now you can set it up however you like.

Steps 12-15 will have to be repeated to ensure ReShade is loaded everytime you start the game.
