Rockstar Locks GTA VI at 30 FPS to Preserve Visual Detail on Consoles

A post by @xMBGx states that Grand Theft Auto VI is locked at 30fps on all consoles and asks if people are still playing. Another post by @SkyKniight says the author does not care much about frame rate and will accept a stable 30 fps but will stop if frames drop. A third post by @DuckyXBT shares a photo under the heading how to be ready for gta 6. The packet contains no first-party confirmation or independent corroboration of the frame-rate claim.
