In theory ?
In real life if they ran for more than a few minutes they would fry, so I guess in theory they would burn up too.
Anyway, I ran fraps while playing and I was averaging between 25 and 40 frames per second, that is at 1920 x 1080 everything on high and 8x AA. Even with those low frames it seems smooth except when I start blowing a alot of shit up at once
