Introduction to Dynamic Resolution

Dynamic resolution is a CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info

setting that allows you to dynamically scale individual render targets, to reduce workload on the GPU. In cases where the application’s frame rate reduces, you can gradually scale down the resolution to maintain a consistent frame rate instead. Unity triggers this scaling if performance data suggests that the frame rate is about to decrease as a result of the application being GPU-bound. You can also trigger the scaling manually by preempting a particularly GPU-intensive section of the application and controlling the scaling via a script. If scaled gradually, dynamic resolutionA Camera setting that allows you to dynamically scale individual render targets to reduce workload on the GPU. More info

can be almost unnoticeable.

Render pipeline compatibility

Dynamic resolution support depends on which render pipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info

your project uses.

Feature Universal Render Pipeline (URP) High Definition Render Pipeline (HDRP) Built-in Render Pipeline
Dynamic resolution Yes (1) Yes (2) Yes (1)

Notes:

  1. The Built-in Render Pipeline, and the Universal Render Pipeline (URP) both support dynamic resolution as described in this document.
  2. The High Definition Render Pipeline (HDRP) supports dynamic resolution, but you enable and use it in a different way. For information on dynamic resolution in HDRP, see Dynamic resoluton in HDRP.

Supported platforms

Unity supports dynamic resolution on iOS, macOS and tvOS (Metal only), Android (Vulkan only), Windows Standalone (DirectX 12 only), and UWP (DirectX 12 only).

Impact on render targets

With dynamic resolution, Unity does not re-allocate render targets. Conceptually, Unity scales the render target; however, in reality, Unity uses aliasing, and the scaled-down render target only uses a small portion of the original render target. Unity allocates the render targets at their full resolution, and then the dynamic resolution system scales them down and back up again, using a portion of the original target instead of re-allocating a new target.
