Mesh Shaders are here! Enabling 4K 60fps on RTX 3060ti with 1.8 billion triangles! (Justice MMO) 

And now, we have this in a game: Alan Wake 2. Just make sure you reference this video!

Mesh shading is something completly different: In a traditional shader pipeline a vertex is processed and passed to the pixel based fragment shader. Mesh shading processes meshlets (a subgeometry of your mesh) with task shaders and then passed to the fragment shader. In a traditional pipleine you couldn‘t have access to a chunk of vertices (unless you use the super slow geometry shader). Now you can access these chunks in the shader and move logic away from the cpu to the gpu. LOD is just a usecase that can use mesh shading.

Two things I'm most excited for in gaming software...(though both seem to be delayed) 1. When DirectX 12 Ultimate and DirectStorage brings to PC the instant load time type features that the Xbox Series X and PS5 have. 2. Unreal Engine 5 and the potential it brings to devs to make the games they want to make.

Even in 2023 we haven't game with mesh shading

Since AMD brought out the 6000 series cards and given the fact that Xbox series x/s and PS5 have the GPU technology going forward it is only reasonable to assume that Mesh Shading will be more implemented in games going forward

I can see it making it's way into more games especially since the Series X/S support mesh shaders, so do RX 6000 series, RTX 2000/3000

If we're going for 4k 60fos on console, then and average somewhere around 600 million-900 million triangles seems more reasonable, especially considering other aspects like lighting. Though that's just for the exact implementations e see here. There is of course a lot of opportunities for improvement as devs get more used to it, which is also supported with UE5's Nanite, which ran at 1440p upscaled to 4k at 30fps on PS5 with roughly 10-20 billion triangles in view at a time, on top of the incredible global illumination. For the last few years I've been a bit disappointed in current games' polycounts, since from 2014 to 2018, they haven't evolved much, with very few games using tessellations extensively, and on top of that the RTX trend shifted the focus even more towards lighting. But this just blew any expectations out of the water. We're pushing dozens of times more triangles with the same quality for everything else, and in a short period of time, which is a good thing to see.

I'm wondering if this can reduce the Vram usage since I got the laptop version whose Vram is no bigger than 6GB.

Well we need a updated video

Yeah. This tech sounds like something real, unlike ray tracing.

I think the unreal 5 engine does something likewise. But if I am not mistaken, it is not necessary to make different LOD levels for each object in unreal 5. If I remember correctly he engine just renders what fits in the pixels available according to your screen resolution.

Wonder if the mesh shaders will allow more photo realistic textures

Nice!

This was a bit of a surprise for me, but for a different reason: games using different lod on mesh models is anything BUT new. For instance, Second Life, which is pretty ancient (and yes, a lot of ppl don't consider it really a game), offers the possibility of different LODs for mesh models for at least a decade or so. Other games have done so as well in the past. So there's probably more to it than just using different LODs, I believe.

Developers just lazy to create LOD like nanites.

With all this tech coming, im hopeful my 6800xt will last me quite a few years at 1440p

What's so special about triangles, can't they throw some squares in there too?

Mesh shaders are overrated. They're trying to get people to move away from the 10-series and RX500 cards. They can pry my 1070 from my dead cold hands! I dabbled into modelling and level design and you can make a VERY NICE scene with 6-8 million triangles and fake everything else with normal maps and parallax occlusion mapping. Just look at these PS4 games: Horizon Zero Dawn, Uncharted 4, Until Dawn, The Last of Us Part 2, Ghost of Tsushima. And they're running on hardware from 2013!

I watched this video 4 months ago I was using a rx580 enjoying my life. this video made me buy a rx6800. now i can play alan wake 2. yay I guess.

Have you watched the Unreal 5 demo ? that s what they provide with Nanite
