The error message "The detected configuration does not match your current hardware" for *Sonic Generations* can happen when you: *
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? My computer is pretty old, so I do run it at a pretty low resolution to maintain ideal gameplay conditions.
Sometimes, running the game in compatibility mode can resolve the issue.
The most common advice on forums is to set your Configuration.config file to “Read-Only” after applying your desired settings. While this prevents the game from resetting the values, it introduces a secondary problem: The error message still appears every time you launch the game. This error is infuriatingly common

If you are a long-time fan of the blue blur, you have likely tried to revisit Sonic Generations—the 2011 masterpiece that blends classic 2D and modern 3D gameplay. However, after upgrading to a new graphics card, a new monitor, or a completely new PC, you may have been greeted by a frustrating pop-up:
"The detected configuration does not match your current hardware. The current configuration will be loaded, but some settings may be changed or reset. It is recommended that you review your settings in the Options screen."
This error is infuriatingly common, especially on modern hardware (RTX 30/40 series, Radeon RX 6000/7000 series, or high-refresh-rate monitors). Worse, the game often ignores your manual settings, resets your resolution to 800x600, locks to 30 FPS, or crashes on launch.
