I've been playing lately and I notices the game is a little sluggish. There's no lag, but it is very annoying. May be worth noting I changed out my processor, memory and motherboard recently. I wondering if anyone has any ideas?

Sometimes the game will pause breifly while unseen enemies take their turns. Does the game stop briefly after every turn, and play the sound of a creature or robot moving? If so, I believe that is normal behavior when there are creatures nearby.

If you're encountering something else, can you describe it in more detail? You said there's no lag, so what do you mean by sluggish?

No, its more like all in-game animations run slower the before I installed the computer upgrades. Sound and everything else seem normal however.

That's odd. I assume that you reinstalled your OS after the hardware upgrades? I'm pretty sure Windows acts strange if you change important hardware like the processor without reinstalling WIndows afterwards, but that should affect more than just this game. Otherwise I don't know what it could be.

I've figured it out! The game now works fine since i uninstalled and re-installed Microsoft XNA. May be worth noting I downloaded a standalone XNA istaller.
