Reshade Setup Basically, just get the ReShade installer from their website. Latest ver. might be 5.9.x something. Run the installer and select TekkenGame-Win64-Shipping.exe (in Win64 directory). Next, select all the shaders to install. Installer will download all the shader files. The preset file you download here can be put in any directory. Though, I recommend you put it in the same directory as Tekken7's executable. Start the game, you should see the reshade overlay loading the shaders. Now, press HOME key to bring up the Reshade overlay/Menu. There search for the preset file and select it. Then the preset is applied. Enjoy!
Uninstallation guide To uninstall, simple delete the dxgi.dll file in the Tekken executable directory.
