Realtime Indirect Illumination using RSM

i dont se shadows...

Looks great.

So, just, virtual point lights, no bounce occlusion? Looks neat.

Very nice, very atmospheric.

Looks good - i've tried some RSM some time ago and then extended it to quite robust solution (with secondary shadows, etc.

Try using small shadow maps for each VPL - this way you'll get some nice occlusion - then you can start doing tricks on optimizing it. Quite good are so called imperfect shadow maps, you can also try different approachs on optimizing shadow maps generation and achieve high performance GI.
