Yea, the rollout for new feature support has been relatively slow. Very few games are based on RT only for instance. I feel like it won't be until next generation of consoles, will all these features be the standard norm.

DX standardized mesh shaders from Nvidias implementation. But you are right that vendor implementation of the spec will be different for all IHVs with their own preferred workloads for optimum performance

But isn’t it the exact specification created by Nvidia? If so it probably isn’t optimal for Non Nvidia GPUs.

This is as I expected. It's unlikely that the hardware is actually different between ps5 and seriesx. SeriesX supports mesh shaders because it uses Direct3D. PS5 does not support mesh shaders because it doesn't use Direct3D, but the hardware has the same capability. PS5 likely just uses...

The ROPs on PS5 are more like RDNA1 ROPs when compared to Series ROPs (half as many, double pumped for most functions).
I hope mesh shader concept is like tcp protocol. Its up to hw vendor how to support it but it doesn’t favor one hw over another.

PS5 obviously has something similar to Mesh Shading. Their geometry engine is likely much upgraded compared to RDNA1, just like Ray intersection accelerators were added. It's likely the primitive shading on PS5 is a lot more sophisticated than what's possible on RDNA1.
Alan Wake 2 confirms the PS5 is using RDNA2.
I've rarely seen people upset by the DX12U requirements. I've seen a lot of praise that Remedy finally ditches old hardware and push the industry forward.
People complain that the system requirements are generally too high and require upscaling.
Also UE5 may use them, but they are essentially useless in this engine. We've had Nanite games in the past and never has there been a performance boost for DX12U compatible cards. I've also checked it personally in UE5 and there is zero difference between mesh shading support on and off.
Remember, Nanite uses Mesh Shading automatically for geometry bigger than a pixel. But since that doesn't matter at all, you may as well say Mesh Shading is not supported by UE5.

I had been trying to preach this as much as possible ever since we learned the console specs(and even before). It was very clear that PC gamers were spoiled last gen and that this gen would not be the same. Especially if 30fps games on console returned, which would likely mean not just quite heavy GPU demands on PC, but also CPU demands that many people would absolutely not be prepared for. I can still remember how many people were extremely confident in telling people how a Ryzen 3600 would be 'totally fine' for this whole generation...
I'm not informed enough to explain in my own words well enough, but here's a good rundown:

NVIDIA just published the performance numbers for Alan Wake 2 with max Path Tracing, at native 4K the 4090 can do 30fps. With DLSS3.5 it can do 134fps. Even a 4060Ti can run this game fine at native 1080p.

There is a lot of info about what mesh shaders are and what they do. But in the biggest tldr mesh shaders is conceptual change to rendering pipeline.
"The main goal of the Mesh shader is to increase the flexibility and performance of the geometry pipeline. Mesh shaders subsume most aspects of Vertex and Geometry shaders into one shader stage by processing batches of vertices and primitives before the rasterizer. They are additionally capable of amplifying and culling geometry."

Cyberpunk was 2 bounces on path tracing right? that says high path tracing uses 3 bounces so that is probably why it's a bit heavier than cyberpunk even thought it's not open world.NVIDIA just published the performance numbers for Alan Wake 2 with max Path Tracing, at native 4K the 4090 can do 30fps.

2 rays, 2 bounces.
The documentation here indicates the optimal way to dispatch work for both IHVs
Interesting. Based on the performance data by Nvidia it is a lot more performant than Cyberpunk Overdrive.
I'm sure we can count on @Dictator to see how well ray and path tracing scale down to lower cards like the 2060 and also how the performance of the game generally is. Atleast for RT, it seems they provide a nice set of options for scalability.
There is a chance the system requirements might've been totally overblown.
