Any reason not to check "application library caching" and "GPU acceleration" in silverlight apps?

When setting the properties for a silverlight app, I see the unchecked boxes:

  • Reduce XAP size by using application library caching
  • Use GPU Acceleration

Smaller download size and faster speed sound good to me, which makes me wonder why these aren't turned on by default.

What are the drawbacks of these choices then?

I believe both of these features were introduced in Silverlight 3. One reason for them being opt-in is to maintain backwards compatibility.

There are instances where turning on GPU Acceleration can actually degrade performance or cause other issues. By making it an opt-in process, you are more likely to notice the consequences (good or bad) as opposed to the setting being turned on by default and wondering why your application has performance issues.
