D896 - A refused dispatch or draw can be passed over to see every wall

Status: decided Date: 2026-10-19

ORBISTOUN_PASS_REFUSED, a diagnostic that intervenes, has the command processor pass over a compute dispatch or a segment of draws that the host refuses, rather than stop its queue there. The refused work writes nothing and the stream goes on to the packet after it. Each distinct refusal is kept with its kind and how many times it was met, and the run report lists them all, first met first.

Unset, a refusal stops its queue as before (D705, D710), and nothing after it retires.

Why: A refusal stops the graphics queue, so a run shows only the first wall the host meets, and which wall comes first changes from run to run as the title's submissions interleave. One Grand Theft Auto V scene held forty distinct refusals: unnamed opcodes, SDWA on float instructions, layered images, runtime-indexed descriptors, and texture formats. They were met one per five-minute run, and a run that stopped at a different one first read as going back. Listing every refusal at once lets them be fixed by the mechanism they share, not one per run.

Rejected:

• Passing over refused work by default: a frame or a result after it is not the title's, and a run under the default measures the emulator (D708).
• Counting refusals without passing over them: the work after the first refusal never reaches the host, so its refusals are never met.
