@GenesisFlux - I think you may be misunderstanding what octagonal constraints does (all the more reason to exclude it as a setting). You can still move the stick in any direction 0-360 degrees, not just 0,45,90,135,etc. The octagon constraint simply limits the magnitude at the very extremes. It's like putting an octagonal fence inside a circle with a radius of 100%. When you push the stick, say at 20 degrees from up, the magnitude is limited to something like 97%. Like the original controller. Like Paul said, some games are strangely sensitive to the strength at the limits, and this just fixes that. There's really no reason it shouldn't always be enabled.
