(the ‘title’ and ‘body’ was AI-fixed cause my English is bad)
The tool would work by:
-
Detecting a specific benchmark level within the game, regardless of the game engine used.
-
Running automated tests on every combination of CPUs, GPUs, and storage types (SSD/HDD).
-
On tool’s servers: Testing against all conceivable hardware specs to find absolute minimum, recommended, and high settings.
-
Locally: Using the user’s current hardware specs as the maximum benchmark limit.
-
Output: Providing the perfect system requirements (minimum, standard, and high) based on these results.
You would need a way to walk through a good chunk of realistic gameplay without user input. Good luck with that.
The closest thing to this right now is the performance monitoring that Valve does for Steam Deck compatibility — which isn’t headless, it’s just crowdsourced.
