### Remarks

Set once when creating the [FSRUpscalerContext](/engine/6000.7/script-reference/unityengine/amd/fsrupscalercontext.md) with [GraphicsDevice.CreateFSRUpscale3](/engine/6000.7/script-reference/unityengine/amd/graphicsdevice/createfsrupscale3.md) or [GraphicsDevice.CreateFSRUpscale4](/engine/6000.7/script-reference/unityengine/amd/graphicsdevice/createfsrupscale4.md). These values determine the internal resolution limits, display size, and operational flags.
