Read available options
Graphics settings differ between games. Use the current game’s own explanation for resolution, effects or performance presets.
Start with a baseline
Note the device and current settings. Play a short repeatable section so the next observation has a useful comparison.
Change one option
Adjust one setting and revisit the same section. Observe readability and control response rather than guessing an exact frame rate.
Keep claims specific
Record the game version, device and conditions. A result on one phone does not establish performance on every device.
