Configuration Does Not Match Your Current Hardware New [better] — Sonic Generations The Detected

Sonic Generations and the Hardware Configuration Lock

Internal developer comments (leaked 2018 Sonic RT archive) indicate the check was designed to prevent from swapped GPUs (e.g., laptop docking/undocking while the game runs). The hedgehog engine’s shader permutation cache was tied to specific GPU feature levels (vs_3_0 vs vs_4_0). A sudden change mid-session could crash. However, the check was over-aggressively applied at every launch , not only on resume from sleep or GPU hotplug.
