It worked fine for me on Ubuntu 16.04 but only gave me around 56 Sols/s (or was it 52? Can't remember) on a GTX 1080. While certainly better than any other Nvidia miner available, it used too much CPU so I couldn't use my CPU to mine anything (or rather, they "evened each other out" making CPU mining pointless) so I just stopped and went mining with Nicehash instead.

Now, regarding Genoil's Windows version, it gives me about 27-28 Sols/s on my GTX 1080 which is about the same as Nicehas's GUI miner does.
