Kinda tired right now, but I fail to see the gain of your technique.

In #1 you do a simple Z only rendering using the light frustum. This is the first step of any shadow mapping. After that I simply do projection in the light shader and I do not understand how adding more steps will speed things up. Also your technique seems to not take advantage of hardware PCF.

I might be missing something though, so please correct me
