I have it loaded on 2 systems both running 64bit Kubuntu one is 11.10 the other is 12.10 and the 12.10 system has an Nvidia 9500 GT. The 11.10 has a AMD 4300HD. Guns of Icarus runs on the Nvidia no issues so far. On the AMD it starts, then plays the first bit of music then restarts the X session. Was wondering if anyone else has run into this?
