Been playing the beta build off and on and for the most part it runs greats on my machine. However I have noticed that every now and then the game hangs for a couple of seconds. Which is rather odd, its not choppyness at all like one might encounter when your computer is chugging to load things. More like the entire game engine itself has decided to hang for a moment before continueing. Just thought I'd mention this since I haven't seen it mentioned yet.
Further note all my testing has been hosting my own LAN games vs AI demigods not players or over the net.
Heres my system specs
Windows Vista 32bit Home Premium
AMD Athlon 64 X2 Dual Core 5600+ 2.8GHz
Asus M2N-E SLI Motherboard
2 Gigs of Corsair DDR2 RAM
Geforce 8800GTS Nvidia Video Card
Integrated Sound Card on the motherboard.
I also use two monitors but since Demigod doesn't support it I doubt its having too much impact.
