Every connection up there will be shifted to fit the 56K narrowband. So DSL or Cable u still will be going about the same as 56K would in that game. No lag since i use 56K as well. IT only lags a bit when u are downloading the NPCs and stuff but its at most 4-6 seconds after the screen has loaded. Trivial thing really.

Now my video card isnt the best and it lags when there is special wheather, but if u dont have the best u can always turn off the effects of wheather appearing in ur screen(theres a icon on the left corner that shows the weather anyway so that helps) and that shuts off lag permenently.
