I thought it was just my old computer not being able to handle the game well (it's nearly 8 years old). I, too, have the stuttering, loading and lag spikes, but other games run just fine. It adds an extra level of difficulty to the game; I have to calculatehow long it will take for my actions on the keyboard to actually happen onscreen.

For the record, I'm on Comcast in Northern New England (USA).

As an aside, I'm not quite sure what sending and receiving numbers I should be expecting. I assume higher numbers are better? Is there some minimum I should be looking for? And (forgive me if this next part is a stupid or unrelated question) will fixing this problem help me have higher FPS (currently, my FPS is 5-7 in town and maybe 12-15 out in the wild)?
