What is dr4?

DR4 (Dynamic Resolution 4) is a technology developed by Unity Technologies that allows games to adjust their resolution dynamically in real-time based on the performance demand of the game. This means that the resolution of the game can be lowered or increased automatically to maintain a consistent level of performance, particularly on lower-end devices or during graphically intensive scenes.

DR4 works by continuously monitoring the performance of the game and making adjustments to the resolution without the need for manual input from the player. This can result in smoother gameplay and a more consistent frame rate, even on devices with limited hardware capabilities.

Overall, DR4 is a useful tool for developers looking to optimize their games for a wide range of devices without sacrificing visual quality or performance. It helps to ensure a more enjoyable gaming experience for players, regardless of the device they are using.
