I am using r.watershed module in GRASS 6.4 running in QGIS 1.4 and every time I run it I get the result very quickly but it is very course. I have tried it in both windows and mac working and they give the same result. I cannot tell if I am doing something wrong but I need to figure out how to get the same result but to match the rest of the data so I can do other calculations on it. I am using LiDAR data of 5ft per pixel.

check that the computational region settings are set to match the 5ft/pixel.
(g.region) This isn't done automatically.
also check that the threshold setting is set to something appropriate.
