No matter what kind of monster system you have, the way that the engine chooses to handle the work loading is still going to cause you to stutter slightly in some areas.
The GameBryo/Netimmerse engine they're currently using is the same one used for Morrowind, and they both use the same method for handling large outdoor areas. All the areas are processed by being broken into large overworld sectors (in the shape of a grid - each sector being 1/4th to 1/2 a square mile, if that). The engine will only load the sector that the player is currently in, and all adjecent sectors during the game. When the player traverses sectors, the game will determine which ones he/she is moving closest to, and load those sectors into memory while dropping the furthest ones out. This is what causes the stutter during the game, and there is just so much info being passed around there it will never fully go away.
Another similar issue I may recall reading about was some wierd object loading priorities (buildings and such popping into view right in front of the player, when the background was already loaded). Smaller objects such as buildings and other details are handled in a similar way as the larger, world sectors. Each large world sector contains info on all the smaller objects within it. As the player moves through a sector, the engine calculates what smaller objects are nearer to the player in that sector, and loads and draws them. If people are seeing things like buildings load in later than larger areas or objects that are further away, I think this would be a design/development issue. It sounds like the game can't determine correct priority for loading world details, or that the PC's can't keep up with the constant request for loading assets as the player moves around. This also means that you should see some improvement with hardware upgrades in this area, though things still might load out of order if Bethesda doesn't work out the kinks.
This is all educated assumption though, so some of it might be wrong. I worked with the Morrowind editor and Gamebryo engine professionally so I thought I'd explain what I saw for the issues people were talking about. I was a bit depressed to hear that Bethesda stuck with the Gamebryo engine for Oblivion though because of the wierd stuttering issues in Morrowind. Morrowind was at least functional if you learned to look past that (which I did, and found an amazing world under it which gave me thousands of hours of adventure), but I don't expect most people to deal with it the same way.
Hope you all enjoy the game at least. I've been waiting for this for a long time.
