There's only a few waves per-frame that see two or more draws when resolving, which are the only cases where the waves aren't fully utilized. This is as good as it can be anyway, if those waves weren't going to shade another draw, they would have been inactive in a "wave-perfect" resolve anyway.

I *really* like the flexibility of this approach while keeping the resolve waves full. With this you can do software VRS easily, both spatially and temporally, which is super cool! You can just write any logic to decide how the visibility buffer values map to a sample to resolve.

Plus you also can select variations of the shaders to further optimize! If a pixel is not seeing any local lights, you can dispatch a version of the resolve shader that has all the local light code compiled out. Or if a pixel is fully in shadow from directional light, nuke all that code too, etc...
