Trying to run this sample but i'm getting error:

dxil-spirv: Unsupported AGS magic instruction 0x36 (immediate 258).
dxil-spirv: Failed DXIL opcode 79.

Most likely skill issue as this AGS instruction is present on the ags wmma header... but reporting anyways in the chance its really an app problem

That points to float8 conversion (uh ...). Is that sample ML-based or something now?

Offers a machine learning-based solution for denoising.

Right ... Well, either way, not high prio until a game ships with this.

makes sense, so far only crimson desert is going to use ml denoiser (NRC was mentioned still unconfirmed), releasing in a couple of weeks march 19th

If there's a real game shipping with this, then that bumps priorities a little I guess.

Nothing extracted yet.
