I see your post, but there are no RT shadows in the video. I saw a lot of PS5 in the last year. I had almost every early sample, and I can safely say that RedGamingTech has no clue what they talking about. Both consoles use custom Zen and custom RDNA based on Zen 2 and RDNA 2. The geometry...

If you are on DisplayPort than only FreeSync Premium Pro and G-Sync/G-Sync Ultimate support propieartary features. All other solutions are based on a VESA standard.

It has the same geometry engine. This unit is also identical on Xbox Series S and X. The APIs are different, but the underlying hardware is the same.

I still don't see it. You have the normal shadows. Certainly, the allocated memory is not needed. But this is the problem of the PC platform. The memory management is inefficient, and the memory usage is much higher than the theoretical needs. So even if you don't need a lot of data, it has to...

I saw it, and the RT shadow is missing from the game itself. The problem is that the RT in Godfall is not implemented inside the DXR API. It's an interop implementation that do the job outside DirectX. You can check the library file inside the game folder: amdrtshadow.dll. I wrote it earlier...

The RT in Godfall is very memory hog. You just don't see it, because it can't be activated on a GeForce in the currenct program version. No matter how hard to try, the service library is missing in your system. As you can see in the benchmark, those are not RT shadows, the overall quality is too...

Programmable traversal can be supported by NVIDIA via shaders. A fixed-function BVH traversal unit never able to support this kind of functionality.

This is true, but that's not the problem. The issue is that when you shoot the ray, you need to set the LOD, and that lavel is applied for the full lenght of the ray. This means some objects far from the camera might be loaded in the highest resolution, while in theory it would be enough to load...

Might be, but not because the hardware. I'm only familiar with the PS5, and Sony's IO/RT APIs are miles ahead of the PC options. What makes me sad is that this is purely a software-based advantage. Nothing stops the newer PC GPUs to execute a custom BVH traversal via compute shader, the hardware...

Don't believe in marketing materials. Their job is to sell the products, nothing else. There are several way to lower the memory consumption. The easiest and most useful way is to limit the length of the rays. This is possible in a standard APIs, and it will help a lot, but the quality will be...

The VRAM usage in ray tracing might be massive. This is because the standard PC implementations don't support flexible LOD systems. Every object must be loaded to the memory with really high resolution, no matter if it is far or not from the camera. The LOD must be selected before shooting the...

The frametime will be generally better, because there are a lot of shader codes when it is not really possible to optimize for a good resource allocation. In this case there won't be enougth warp/wavefront to keep the ALUs busy. The data access latency is simply too high. With Infinity Fabric...

Worse. Hit rate will go up with bigger cache size, and/or lower resolution.

You mean ray traced audio processing? That's a focus point on the next gen consoles, but not really on PC. But even it's not on the focus, the technology is there. Steam Audio 2.0 is mostly can do what the new consoles can. Not a perfect match, but it can do the job. Now Steam Audio 2.0 support...

I think there is a lot of misunderstanding, maybe the source of this is how Sony and Microsoft detailed the new technology. Yes, consoles are designed to manage the data much more efficient, and this is done by several, more or less individual components: The IO API, DirectStorage for example...
