Dynamic resolution is a Camera setting that allows applications to automatically adjust rendering quality to maintain performance.
According to the provided reference, Dynamic resolution is a Camera setting that allows you to dynamically scale individual render targets, to reduce workload on the GPU. This feature is primarily used to optimize application performance, particularly in graphics-intensive scenarios.
How Dynamic Resolution Works
The core concept behind dynamic resolution involves adjusting the resolution at which parts of a scene are rendered in real-time.
Here's a breakdown:
- Scaling Render Targets: It focuses on individual render targets, which are essentially memory buffers where the graphics output is drawn before being displayed on screen. Dynamic resolution can dynamically scale the resolution of these targets.
- Reducing GPU Workload: By reducing the number of pixels the GPU needs to process per frame (by lowering resolution), the workload on the GPU is reduced.
- Maintaining Frame Rate: The primary benefit is achieving a more stable performance. In cases where the application's frame rate reduces, often due to complex scenes or demanding effects, you can use dynamic resolution to gradually scale down the resolution to maintain a consistent frame rate instead. This provides a smoother visual experience, even if the image isn't always rendered at its maximum possible resolution.
Benefits
Implementing dynamic resolution offers several advantages for applications, especially games:
- Improved Performance Stability: Prevents drastic frame rate drops, leading to a more consistent and enjoyable user experience.
- Optimized Resource Usage: The GPU isn't forced to render at maximum resolution constantly, freeing up resources when the demand is lower.
- Adaptability: The application can adapt to varying hardware capabilities and changing scene complexity without user intervention.
In essence, dynamic resolution acts as an automatic adjustment mechanism, trading off some visual fidelity (resolution) for smoother and more stable performance when needed.
