Stupid Question About DOF

Recommended Posts

If I increase or decrease the DOF with FDOF or NDOF ( far and near ) does it increase or decrease performance by using it. I assume that just the fact that I am using it in the first place, it would decrease performance but I want to know for sure.

All of these full screen post effects are working on a per pixel basis, which is why the number of pixels is the most important performance factor. In the case of DOF it is always working on all pixels, so it doesn't really matter what near and far distance you set.

It might be that the per pixel calculation gets more or less complicated when you change near and far distance, but that would be not a huge factor.
