Dynamic shadows artifacts

I’d tend to agree here. It is just that the actual performance gain is hardly measurable. This is mostly due to the fact that large part of 4 in 1 comparison gain is the actual 4 in 1 texture fetch, which is already used. It boils down to 1 MAD and 1 SUB instructions less minus cost of hardware comparison per 4 samples, which is… well… not much these days, but still something.

But following the same logic, I’d say that ditching whole TransitionScale, and letting user tweak the depth bias per-cascade(not a replacement for slope-scaled bias, just alternative approach to the goals, that are set for existing system) would be good alternative, don’t you think?

Yeah sample Gather is used SM5 platforms but not on mobile. IOS supports: sample_compare(), gather() and gather_compare() fetches.
