02Normative procedure

  1. Fix the rig: reference hardware per Minimum and recommended, current drivers, passing Vulkan check and AVX2 probe.
  2. Fix the software: build from Download Meridian, official PS5UPDATE.PUP via File then Install Firmware, owned dump indexed per Index your library.
  3. Warm the cache: run the same route, lap, or sortie twice. The second pass is the measurement — see Shader cache.
  4. Run the session: full sessions for Stable candidacy, end-to-end with notes for Beta, menus plus early gameplay for Test — per Status definitions.
  5. Record evidence: build number, firmware version, GPU driver, settings, and observed defects. Without evidence the run did not happen.

03Promotion and regression rules

  • Promotion requires repeated clean runs across sessions, not one good evening. Single runs promote nothing.
  • Regression on re-verification drops the rating immediately and is recorded with the causing build.
  • Ratings never transfer across builds silently. Each build re-verifies the Stable titles leaders first.
  • Own your library: method runs use owned dumps only. 400+ titles indexed; each earns its rating separately.

04Questions

Q.01How many runs promote a title?

Multiple clean sessions under identical conditions. One clean run is a candidate, never a promotion.

Q.02What evidence must a report include?

Build number, firmware version, GPU driver, settings, and warmed-cache runs. Missing any, unactionable.

Q.03Do faster rigs earn faster promotions?

No. Ratings follow the reference rig so results compare across users and builds.
