   [DX10] Do multiple VB streams affect performance?
  Hello,I'm redesigning my geometry loader code and before I proceed I'd like to know if binding many vertex buffers to the IA stage has an impact on performance.In my current (soon to be 'previous') implementation I combined sever vertex data streams into one: I had the position stream as the 1st stream, texcoords and normals combined into the second stream and optionally other streams(eg normals and binormals into another one).For this implementation I was thinking of separating everything into its own stream as this would simplify loading and input layout creation code and make it quite flexbile.Would there be a performance impact?   
  There will likely be a performance hit, but you'd have to test it to see how much it is. It'd probably not be very large.   ;  Ok, thanks
