I can't help but think you all might be let down by the next gen specs when they drop.... Either that or get ready for $600 USD for the next gen which suits me fine but the PS3 launch looms large in the mind of Sony.....

Did you know the cell could do raytracing aswell?

Instead of seeking to convince others, we can be open to changing our own minds, and seek out information that contradicts our own steadfast point of view. Maybe it’ll turn out that those who disagree with you actually have a solid grasp of the facts. There’s a slight possibility that, after all, you’re the one who’s wrong.

Well, if I'm not gravely mistaken, this is a bit apples to oranges comparison.

Demos and games on nVidia RTX cards use path tracing, while Crytek are using Sparse Voxel Octree Total Illumination (SVOTI, which is more or less SVOGI...invented by nVidia, no less), which uses voxels to approximate scene geometry and than casts cones onto them.

I don't expect to see much of DXR and RTX type of things next gen, maybe for few crucial things here and there, but I fully expect to see SVOGI - right about the time this gen kicked in, Epic was building SVOGI as a main lighting system for UE4, but due to consoles being underpowered they dropped it at the end, to re-implement it at later date (UE4 currently supports it to my knowledge). Next gen consoles will definitely have enough juice to use it properly.

Lately, Metro was all the rage on RTX cards, but I was secretly hoping for some company to do exactly what Crytek did - show how much close to "real" thing you can get with voxel based approach. Of course, there are things that will not be as good as with true ray-tracing, but I think it's fairly good approximation.

Ray Tracing is inherently a compute limited problem... Ironically one of AMD's greatest strengths in GPU design.
We started down the path of Ray Tracing with Path Tracing during the 7th gen. (Might have been some dabbling in that space in the 6th gen with a few early deferred renderers? Not sure.)

Goes without saying that next-gen we will start dabbling more in Ray Tracing... And during the 10th gen we will more or less be in a fully ray traced world or close enough to it anyway, hopefully by then AMD has all it's GPU ducks in a row.

I mostly hope in gen 10 we'll be fully in voxel based worlds (or some variation of it), all else IMO will then, more or less,, come by default.

Yes it is much better to get good enough for a very small fraction of the cost.

I would expect they to use ray tracing on preparing either pre-baked effects of better quality or for creating cutscene
