Developer reruns Opus 5.5 Lander remake nine days later and reports regressions
A developer used the same prompt and reference images to have Opus 5.5 one-shot a remake of the classic 3D game Lander on launch day and again nine days later, reporting clear declines in rendering, physics, menus, bullets and camera controls.
The Opus 5.5 nerf debate just got receipts. on launch day, a dev had Opus 5.5 one-shot a remake of Lander, the classic Acorn Archimedes 3D game by Elite creator David Braben. he saved the exact prompt and reference images, then ran them again 9 days later. what he says got worse: * rendering → props now snag and glitch as the camera moves * physics → the ship no longer breaks apart on crash * the menu → the intro controls screen is gone * bullets → spawn at the back of the craft and clip through things * camera → no more camera toggles his setup: → same prompt, same reference images, a fresh workspace → Opus on Extra High effort both times → he says the gap is too big to blame on randomness Reddit: https://www.reddit.com/r/ClaudeAI/comments/1wvwipe/evidence_opus_55_today_vs_launch_regression_with/
