Crytek demo DXR on Vega 56

[humbug]

@humbug Thanks for posting the Star Citizen video. I watched the whole of it. It was lovely to recline in my comfy chair and become immersed in the game world, which at times, did seem like a modern sci-fi movie.

I had a genuine wow moment when the first transporter/shuttle turned up, maybe because I wasn't expecting it/haven't seen much in the way of footage before, but a great scene nonetheless.

I'll try the Crytek demo later but I don't expect much with my aging video card.

Yeah, perhaps its just me getting old but i'm done with AAA first person shooters, these days i like to relax and immerse myself into a beautiful scenic world where i'm free to do my own thing, that's exactly what i have found in Star Citizen.

Its still very much in development and has a long way to go, but there is enough there to make me happy for hours on end.

Shameless plug, again

Single player campaign mode Squadron 42 teaser trailer.

And just some big ships...

Why is it a dead end? its hardware agnostic and far more efficient. i would argue this is the future...

So a non industry standard that doesn't use Microsoft's DXR is the way forward?
I for one would disagree.

I can see a danger of different game engines using their own versions of raytracing rather than a single standard way of doing it.

Something that can be used on all GPUs is always good - but this has several disadvantages in its optimisation compared to the end game with the kind of ray tracing that DXR/RTX is aiming for - for instance performance wise you have to build simplified representations of your geometry which comes with its own set of limitations especially when supporting features beyond the more primitive/core functions of ray tracing.

My intention isn't really to knock it - it is good for what it is and would be a great stop gap but people are hyping it over other techniques as if it kills them when those other techs are ultimately more advanced and more suited to future rendering tech.

That's ok though, because it will work on all cards. Any which way this goes no one will be left in the dark everyone can try ray tracing. The Non RT fixed function ray tracing methods just re-use raster cores, so the performance more typically follows the percentage you see in other types of games to a degree - although there seems to be some area where it doesn't.

Even though the RT and Tensor cores are not used in this Crytek Ray Tracing demo, the 2080ti maintains nearly 100% performance lead over the 5700xt, which the 2080ti does not do in most conventional games.

If anything, developers doing their own non Nvidia styled Ray Tracing implementation looks like it's actually helping Nvidia because it makes AMD's cards look weak.

Its not about performance though. it is a case of, do we really want half a dozen different methods of trying to do it, and another 5 years or more of dithering about until everybody finally gets in line behind Microsoft's DX12.
That is without even thinking about hardware acceleration, which with loads of different methods will be held back massively. Now NVidia have shown their hand they are going with Microsoft's DXR. What will AMD do with their hardware acceleration that is supposedly coming next year? I would bet they go for Microsoft's DXR as well, leaving anything that isn't using it out in the cold and certainly not the future of the tech.

Raytacing is an Industry standard, RTX is an industry standard, Cryengines Raytracing is just Raytracing, DXR is just an MS fluff name given to an old existing Industry standard that Nvidia have brought to the lime light by hardware brute forcing it and then branding it RTX.

All Crytek did was put some development time and R&D in to optimise Raytracing, not at all dissimilar to how LOD works for 3D Meshes, something Nvidia could have done had they chosen the rout Crytek did. some one somewhere started LOD 3D meshing, now every game has it.

There is no such thing as "Nvidia Style Raytracing" its just Raytracing. here's more of it.... Also a downloadable demo. http://www.rigidgems.sakura.ne.jp/index_en.html works on any GPU.
