Sonic Generations The Detected Configuration Does Not Match Your Current Hardware New

The error is triggered exclusively by the SonicGenerations.exe file performing the hardware check. However, the game also includes a SonicGenerations_Config.exe (the launcher). By bypassing the launcher entirely, you bypass the check.

The game is trying to load an old resolution or graphics setting that doesn't exist on your current setup. By deleting the configuration file, you force the game to create a fresh one that matches your current hardware.

For 90% of users, Solution #2 (deleting the config file) or Solution #1 (the manual launch trick) will fix the error immediately. If you are on a gaming laptop, Solution #4 (forcing the dedicated GPU) is mandatory.

If you are still stuck after trying all seven solutions, the issue likely lies with something unusual like a custom Windows installation or external GPU enclosure. In that rare case, skip the native launcher entirely and use HedgeModManager—it was built specifically to solve this exact problem.

Now, go finish that Chemical Plant Zone run. The error has been defeated.

The detected configuration does not match your current hardware. I get this critical error while trying to launch the game, but only when connected to a TV through HDMI. The game still boots regularly when it's just my computer. Am I running it at a resolution that my TV / HDMI doesn't get along with or something?
