realtime(ish) dynamic radiosity

i got 0.5f fps, but i managed to pull out radiosity in screen space with area light, if i use a pin light maybe ill get slightly better speed... but here it is, note im getting TONNES of BUGS in the render!

I use the same technique as I got ambient occlusion with, this shot is 2 collect passes of the screen... with more collect passes it would look alot better too!

This is dynamic light + dynamic geometry radiosity. :)

Heres a movie of it in action, sped up about 6 times.

What good is this technique for real time applications when it only achieves half a frame per second at those resolutions? Maybe you should look at instant radiosity, screen space directional occlusion with indirect bounce, or light propagation volumes.
i need a faster video card.
What card do you have ?

You can also have a look to 'A Fast Deferred Shading Algorithm for Approximate Indirect Illumination'

check this one out, i had to push the ray so it would get from one end of the room to the other!
