Well, I didn't quite get that. My 3dsMax settings are standard, as I supposed the same as everyone else, set in gamma 2.2 for all input maps. Corona by default also works and show the result in this space.
So is that enough to get benefit from framebuffer downsampling ?
Also, what is the average performance overhead for this ? Does it affect render times ? I once again barely remember it had mostly to do with memory consumption.
