All games and cards are tested with the drivers listed above—no performance results were recycled between test systems. Only this exact system with exactly the same configuration is used.
All graphics cards are tested using the same game version.
All games are set to their highest quality setting unless indicated otherwise.
AA and AF are applied via in-game settings, not via the driver's control panel.
Before starting measurements, we heat up the card for each test to ensure a steady state is tested. This ensures that the card won't boost to unrealistically high clocks for only a few seconds until it heats up, as that doesn't represent prolonged gameplay.

Each game is tested at these screen resolutions:

1920x1080: Most popular monitor resolution.
2560x1440: Intermediary resolution between Full HD and 4K, with reasonable performance requirements.
3840x2160: 4K Ultra HD resolution, available on the latest high-end monitors.
