if and when hardware accelerated openGL has the capabilities to display hdri lighting in real time or 32 way par. floating pts, or superfasst hardware texture rendering.... Imagine then what software rendering will be capable of.... the two will never equate in anyway. and frankly i'm happy with current hardware capabilities. not i ever see the need for real time hdr... since they will not be final product... in any case, at my level (and i'm sure many of us here on sm) the capabilities of our current hardware is more than enough.
