   [SlimDX] What does Effect.Optimize() do?
  What exactly does Effect.Optimize() do?The name suggests that it would make the effect faster in some way, but after calling Optimize() I can no longer call GetVariableByName() on it:var xWorld = mesh.effect.GetVariableByName("world").AsMatrix();would return null for example.   
  Do you mean Mesh.Optimize?   ;  Effect.Optimize() optimizes the memory usage of you effect. This is the reason why you can't get variables after that. When you want to do this, you MUST get all variables BEFORE you optimize it. They will be still valid after optimizing the effect.   ;  Ah, so that's how it works, makes sense.Thanks :)
