Like I said before I calculated halfpixel using the following code: output.position.xy += halfPixel; But halfpixel is equal to Vector2(-1f / destination.Width, 1f / destination.Height)); Be aware that the first value is negative. I forgot to mention before.

That said: position.y = -(input.TexCoord.x * 2.0f - 1.0f); The x should be y.

The rest seems fine. I you want to improve performance you can avoid the matrix multiplication in the world position calculation. Ask me if you want.
