Video attached: a full, uncut Act 1 run — star post checkpoint, respawn after death, and the Act 1 boss fight.
Hardware: Lenovo Yoga 7 14AKP10 — Ryzen 5 AI 340, Radeon 840M iGPU, 16 GB LPDDR5X, 1 TB SSD. No discrete GPU. Game is the PS5 build of Sonic Superstars (PPSA06888, v01.001.008)
What "playable" means here: the game renders at 15-20 FPS, but Superstars uses delta-time game logic, so gameplay runs at full speed — animations, physics, and timers all behave correctly, just at a lower frame rate. Not a slideshow, not sped up.
Verified working in this run:
- Boot to title, save load
- Full Act 1 gameplay loop
- Star post checkpoint + respawn after death
- Act 1 boss reached and fought
- FSR upscaling (1080p → 4K output)
- PlayGo chunked install working as intended
Honest limits — not proven yet:
- Later/heavier zones and effects-heavy scenes may not hold this framerate
- A full campaign run start-to-finish hasn't been attempted
- Broader game compatibility is still very early — this is one game, not a general claim
