@3run seems the manual tell the half of the truth. They forgot to add; "
For the best experience, requires an Nvidia branded card supporting DLSL technology."
Demo seems to run perfectly fine now. I get around 500 fps with normal resolution (drops down to ~200 when tentacles are near by).
In normal resolution effect reminds me somehow of the spider webs, looks nice man! When pixelated, it looks like white noise, but only green in color.
