Silverlight out of browser updating

It works well when you're wanting to use the GPU to execute transforms on a piece of your UI that isn't changing -- for instance, if you have a picture that you want to animate, squish, rotate, etc.
But bitmap caching/GPU acceleration (in its current implementation) slows things down pretty dramatically if you're continuing to update the visual tree inside the part of your UI that you'd like to cache/manipulate.
I guess this could make things worse for other graphics-intensive apps running at the same time. If the graphics card doesn't have enough video RAM to cache everything, I assume Silverlight will degrade gracefully and will just use more CPU cycles to re-render the UI.
Thanks for your help, Richard After experimenting a great deal with bitmap caching, we ended up turning it off in our application.
However, sometimes the browser's history (cache) of temporary files and cookies may contain corrupted information that needs to be cleared to allow Navigator Web II to function properly.
Click here for instructions to clear the cache in the most popular browsers or to display scrollbars on Mac Books.
If it was always beneficial, I assume it would be enabled by default.
I found this similar question with a good answer by Anthony WJones: So one downside is that it uses more video RAM.
Or am I going down a completely different path than what you are asking?
