Modern and Future Geometry Rasterizer layout? *spawn*
- Thread starter Digidi
- Start date
Nanite doesn't do any ray tracing against polygons, but I'm quite certain they do trace against other surface representations. (Ray,cone or sphere against voxel/distance field.)
There are ways to get same effect with rasterization..
Although it would become quite messy..wouldn't it? (Something like depth peeled splatting of distance fields and voxels?)
They also have some form of feedback loop to get the 'infinite' bounces happening.

A funny moment i captured, was at the PS5 event. Marc Cerny is saying that higy plygon count will result in less power consumption than when you use simple polygon models.
For example he is mentioning Horizon Zero Dawn which have low polycount maps, but it is consuming a lot of power.
Also if you look at the layout of the PS5 with high clock speed but less shader they are going indeed to high polygon model?

What are the chances that Simple Geometry (especially in the case of a map screen or menu screen) would cause really high framerates and therefore increase power usage?
As polygon size goes down, so does GPU utilization.
There is limit how many triangles can be rasterized or rendered at same time and how many pixels must be in flight for all units get work.
It's quite common problem in games when v-sync is not enabled.
Always fun to have fps counter on and see few thousands of fps and hear fans pick up the pace.
Her is a Patent for Micropolygon Rasterizer, so if the Poylgon is smaller than a Pixel it will be handeld to a special Rasterizer?

The proposal seems to give the possibility for there being multiple size thresholds, and assigning primitives to a rasterizer dedicated to that size range. A quad seems to be one particular size of interest.
It's from 2016, though I haven't seen mention of it being used.

I'm confused. At 3:40 the guy from Epic introduces Lumen with talking about RTX. But it does not become really clear if they use it or not.
I assumed for sure that Lumen was confirmed to not use RTX.
Did i get this wrong?
It doesn't use "RTX". RTX isn't acronym for raytracing.
Lumen uses software raytracing for indirect lighting

I want to bring back this discussion. I wonder which new features the 4090 and 7900xtx have for geometry output. And what are the current state of primitive and mesh shaders. Anybody has an idea and can make a summery where we are?

How mesh shaders are implemented in an AMD driver
In the previous post I gave a brief introduction on what mesh and task shaders are from the perspective of application developers. Now it’s time to dive deeper and talk about how mesh shaders are implemented in a Vulkan driver on AMD HW. Note that everything I discuss here is based on my...

Maybe I'm stupid (I am) but I couldn't get the D3D12 path to work. It would just open and close instantly.
this was when the first PS5 model launched, right? I remember a DF article mentioning that the power consumption of the PS5 was 220W, which I found too high. Did that number change in the recent revisions? It's not justified nowadays. Judging from the new GPUs I've seen the PS5 should be around 140-160W at most.

The new versions use 20-30w less than the launch model.

Anybody can do the normal vertex shader benchmark on a 4090?
Here are same vlaues from Basix for the 4090. Thank you @basix for the Test

Also i'm wondering. When you use compute shader for primitives, Is this value not misleading? If you use compute Shader mybe shader also occupied by other stuff like lighning. Maybe then the advantage of compute shader would be a disatvantage in real world test?

Here is also a good benchmark tool for geometry. Maybe sombody will try if can render the 4.000.000 astrorides with mesh and with compute shaders? My GPU will not start becasu it is to much for it XD
If you want to increase the polyogns use LOD Bias 6
Also don't close the small message which pops up other wise you can not run the benchmark.
Short Info. The Test is not running on Vulcan when you select Sensor and Info at my computer.
