VXGI...I finally could achieve first results...this lib from NVidia was most complicated and undocumented for me...There is still lot of questions, flaws and just weird things, but I'm very happy that I could force it to work. Right now it does not respect directional lighting - need additional coding for both sides shaders and hook, but...just....finally, last 3 month I tried make this thing works, everything was fine, except irradiance, this one just not worked no matter what I did, and finally...almost crying XD
First picture with VXGI on, and second one with VXGI off. And there is a few pictures more:

VXGI realtime global illumination and heavy enough to eat some performance, moreover I found that my PC is real potato-PC, I'm still using memory, as I found, XD, DDR3 with 660 MHz - just shoot me in the face....there is a lot of work with VXGI still should be done, some experimenting, defining customizable parameters and so on, but perhaps I need update my PC, finally, reinstalling all this SDK's scare me a lot, so maybe it will take some time.
Anyway, Happy New Year for everyone who will see this, I wish you goodluck and success in new year!
