Fresnel reflections and Locked IOR does not look like before

[Jedihopper]

I noticed something strange, I was about to rerender some files I did last year, but now when I open that file and render it does not look the same at all, It looks like the Fresnel reflection is changed it value and it does not look the same at all.
I also open my first max file that I used as template and that file does not have the same materials to it. I uses Vray 5 2.3 Max 2023 and windows 11. But the problem was when I check render from erlier this year it was also not right. What has happend, was there some update that changed the settiings?
