NOTE:

I've tried to make this preset the most performance friendly possible.
Using it combined with ENBoost makes it very playable on most rigs.

Installation and configuration:

Install last Reshade. Copy your owned qUINT_RTGI shader into reshade-shaders folder.
Unzip preset to the game executable folder. Overwrite everything.

Now the tricky part, start the game (YOU MUST BE IN-GAME AND NOT IN THE MENU) and hit the HOME key for the Reshade overlay to show up.
Enable the DisplayDepth shader.

Now, if you can see the left half of the screen in weird colors and the right side y greyscale then it already works,
turn off DisplayDepth and enjoy.

If you see a complete black screen, click on Add-ons at the top of the Reshade window and you will see all the depth buffers,
you must click on each one of them until you can see the left half in weird colors and the right half on greyscale or black. If you can see the half-half color-grey then go back to Home and turn off the DisplayDepth shader. Done.

Now, if what you see is a black right side, go to the Home section, disable the Performance Mode, click on "Edit global processors definition", change the value of RESHADE_DEPTH_INPUT_IS_REVERSED from 0 to 1, and  click on "Edit global processors definition" again.
That should do the trick, enable the Performance Mode again and disable the DisplayDepth shader. Done.
