The reach table of xna4 looks disappointing.
The first thing we can see about delayed coloring is you. I will keep following your blog.
Let's have a look. If we really don't have shader, let's say, don't let us be hung up.
Reach-based
The MRT was tested today and is not supported unexpectedly. Others do not support batch rendering. The size of a texture is limited to 2048. In many cases, the size of a texture must be set to POW 2. But these who care.
MRT exceptions are not supported, while batch rendering exceptions are not implemented.
However, reach supports vertex texture and Shader Model 3 on PC.
This is different from the table provided by Shawn. Although vertex texture was passed in as an effect parameter in my tests. The Direct setting interface is indeed not supported.
I hope it is not just a bug.
