public static float renderViewportScale { get; set; }

Valid range is 0.0 to 1.0. This value can be changed at runtime without reallocating eye textures. Therefore it is useful for dynamically adjusting eye render resolution. This value cannot be changed while cameras are being rendered. Attempts to change the value during rendering will be ignored and an error will be logged. Changes made during gameplay updates won't be applied until the next frame.

Some XR platforms may not immediately use this value.

This value does not support deferred rendering. Attempts to change the value in the presence of a camera using deferred rendering will be ignored and an error will be logged.
