It runs similar here compared to Kiyaku's info. But I consider Unigine a weak engine. It is just too slow. Did you try the free camera mode? Even when fps is over 35 fps it is very jerky.
Compare this to Crysis or similar but much bigger games with animated stuff, AI and physics. Unigine is too expensive and too slow.
The shadows are heavily flickering.
By the way. I tried both DX 10 and DX 9. DX 9 was a bit faster.
