And I liked a lot this tech demo, is awesome! ^_^ I'm pretty sure it taked hard work.

Also here in AMD I barely see reflections when in Nvidia I see fully reflected all the room and all the stuff. I guess it's just that you made this focused for Nvidia GPUs. I understand it, just it's a pity, I'm not finding much demo technical for check my AMD GPU capabilities. Between these capabilities the ray tracying. ^^

In any case it looks awesome the demo sir.

I have tested an RTX 3060 (That belongs to my sister) and my actual GPU is an RX 6650 XT.

I see it's pretty big pity to do not find these kinds of stuff that mention AMD. All of the demos or benchs always mention Nvidia, I have no issues with Nvidia, I'm glad Nvidia has people working in their GPUs creating content. The issue is when I decided to trust in AMD and sometimes most of people never mention or optimizace correctry for AMD.

I checked that both GPUs works Ray tracying, but in AMD some materials feels stranges and specifically I realized that reflections are pretty weak in comparison to the Nvidia GPU, so I ask why does this happen?

In the picture in RTX that cristal seems grey or without colour but in ADM is cleary green/blue.

I made some tests:

RX 6650 XT with drivers adrenaling 23.5.2  I got:
      In Medium Settings 19.37 Avg FPS

RTX 3060 with drivers 531.79 I got:
     In Medium Settings   27.98 Avg FPS

I have been testing my Computer and my sister's computer.
I guess the AVG FPS is the score*
RX 6650 XT  Drivers adrenalin Edition 23.5.2 | FHD:
     Usual Settings  score: 31.51
     High Settings  score: 21.33

RTX 3060  Drivers 531.79 | FHD:
      Usual Settings score:  42.86
      High Settings score: 29.53 FPS

It's clear that Nvidia in this case overcome aproximately 10 Extra FPS to the AMD GPU, but in my gameplay testings made pretty much stable to play fast with the virtual man in AMD when usual Settings were used. The technology anti-lag allowed that I could make friendly gameplay using AMD. When Nvidia had pretty cool FPS to be playing but simply I had a little latency when Reflex it isn't activated. I don't know if Reflex is possible to activate it in this bench demo. I don't use my sister's rtx 3060 much for obvious reasons, it isn't mine.

They are not exactly pure ray tracying. Being exact the real ray tracying only is present in movies already, but the "gaming" ray tracying is only usefull for GPUs that were designed to be able to run Ray tracting decent good. That's why they decided to call them RTX, it's an important change. So when you test your Java edition with shaders that simulate pretty well ray tracying it looks great as skyrim or GTA V with mods that made them look absolutely realistic, they aren't native ray tracying. Minecraft bedroock edition, the Minecraft RTX use natively Ray tracying. I recommend to check quake RTX for example, you would see if you activate RTX on (if allow you to do it) and check ray tracying. In general shouldn't work or run very slow. This is how when Nvidia implemented Physics for first time, old GPUs when tried to run Physics were working suddenly of for example 60 FPS to 5, 2 FPS... Or the game crashed. There it's the point.
