EDIT:
showed this to the coders and this was the response i got:
yea yea
that's what we used to set it up in the first place
its literally the only xna deferred tutorial
Also note we are not using XNA, we are using SlimDX, not sure if that matters at this point. I guess the big issue is that we are using Log depth, and this tutorial and others are not. We are attempting to use log depth to create better precision... but not sure if that is the main reason as to why ours does not work when others have no issues.
