Microsoft Standardizes Shader Execution Reordering in DirectX: Intel Arc Sees Up to 90% Ray Tracing Boost

[David_Schroth]

Ray tracing performance on PC just got a quiet but significant push forward. Microsoft has officially standardized Shader Execution Reordering in the DirectX Agility SDK 1.619 release, making SER a required feature in Shader Model 6.9 and opening a path for GPU makers to expose its benefits far more broadly than before. The performance story […]

Oh now THAT is something. Very interesting.

Now what we need is all GPU vendors to release SER ready drivers so we can have a proper showdown.

EDIT: OK, this is a bit worrying: https://devblogs.microsoft.com/directx/shader-model-6-9-retail-and-more/

Intel has the best coverage of the new features sans one (OMM) but one of their preview features is only available on Lunar/Panther Lake iGPU.



I have a bad feeling about this. I hope this doesn't mean that there won't be any future dGPUs from Intel.

Ok, what about AMD's improvements?

Yea I am a bit curious how AMD was just ignored here.

I got turned off when I saw: AMD Radeon™ RX 9000 series supports API but doesn’t reorder.

I have a RX 9060 XT. Not acceptable when Intel is doing it.

From the Tech Spot article

Nvidia introduced SER with the RTX 4000 series GPUs in 2022 and doubled the feature's efficiency with RTX 5000 GPUs. Microsoft previewed SER's standardized implementation in DirectX last year but has now made it a mandatory component of Shader Model 6.9.


This will make implementing the feature easier for developers and extend its benefits to Intel Arc Battlemage. AMD Radeon RX GPUs currently do not include hardware SER support, but future generations likely will.

Well ****..
