I'm working on a patch based on "The Video Processing System" tutorial by Andrew Benson.
I have a doubt here.. what if after all this processing done with the shaders on the GPU I wanna insert something like.. the Debris example (Recipe 27) in the chain ? Or any other kind of processing the requires operations on a matrix ?
Moving back to CPU is gonna kill the fps?
I hope someone can enlighten me on the use of matrix operations and shaders in the same processing chain.
