Radeon Chill is a power-saving feature found in AMD Radeon graphics cards. It automatically adjusts the frame rate of a game based on the player's activity, reducing power consumption and heat generation when the action slows down. This helps improve battery life in laptops and can lead to quieter operation. By using Radeon Chill, gamers can enjoy a smoother experience without sacrificing performance. The feature is particularly useful in less demanding scenes, allowing the graphics card to operate more efficiently. Users can enable or customize Radeon Chill settings through the AMD Radeon Software interface.
