Photorealistic Resource Pack looks not like in the Pics from the Website?!

So ive dowloaded THIS RESOURCEPACK!
https://matteorizzo.com/realistico/

My PC:
https://www.your-it-world.de/device/764-jayk0b-gaming-tower-gen-2

So, ive "installed it".
I put it into my resource pack folder.

I have the new SEUS Ray Tracing Shader also installed....

and it looks shit.

So you could say WOW looks good?!

No.....
Check the Wesbite, its not even close.

Do i need to setup something right? Because ive looke through EVERY option in the shader....
