--- Comment #4 from Josh Gargus <registration-bugzilla at schwa.ca> ---
Thanks Jason!  

In general on NVIDIA, it seems faster to store values in registers than shared
memory, *unless* there is not enough register space and it needs to spill the
data elsewhere (to main GPU memory? to some other cache? I have no idea).

In this case, it seems that making roi shared reduces the register pressure
enough that depth can fit in registers; as a result, making depth shared
reduces performance.

At least, that is my interpretation.
