What graphic engine is this game using ?

[Dyna]

Is it Unity? And how is the performance on a cpu with 8 or more cores?

Its custom, OpenGL I think and performance is very good with i7s or better. Not sure about 4 core CPUs / i5s or older AMD chips.

A beautiful one.

I dont know what the engine is, I could not find much info on it. I can say it runs silky smooth on an 8core FX 9590 with 16 gig of ram and an AMD R9 290 graphics card & SSD

If all you want is high framrate gaming at 1080p on even the latest games, the hardware above may be old but it packs a punch and for $400 to put it together its a bargain.

Bit hungry on the electricity mind. ;o)

Their own engine good.

Got worried when i saw dual-core in requirements as i already got a few of those games with very poor performance when there is alot going on because the developers are too lazy to support multithreading.

Knowing that i dont risk cpu usage of 10-15% and that it support my system i will give this a go.

DracoNB is right, lemme quote the koon himself from official forums:

No engine, I wrote this stuff myself in c++.
I'm using a bunch of libs though, directx earlier, SFML (replaces direct sound and input now), openGL in the future, lua, and boost.
DirectX will be removed, as it works only on windows, and openGL can do everything directx can.
