Dependency property identifier field: TextRenderingModeProperty
By default, Silverlight optimizes text for readability. Although this is usually desirable, it can have a large performance impact when you animate the scale or rotation of text. This is because changing size or rotation results in recalculating how the glyph is most legible at that font size and position – and an animation changes that size or position 60 times a second.
When animating the rotation or scale of text, you will likely get better performance by turning off this readability optimization by setting the TextRenderingMode property to RenderForAnimation and then setting it back to Default when the animation ends.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
