Here is the updated code.
Changes Made:
* Resolution Selector Added: Users can now choose between 720p, 1080p, 1440p, and 4K. The math adjusts the FPS accordingly (e.g., 4K is much harder to run than 1080p).
* "Show FPS" Button: The long list of games is hidden by default. A button appears at the bottom of the result summary to reveal the list.
* Performance Logic: Adjusted to account for resolution scaling.
