I just conducted a console experiment, for those interested in the running capability of the system.
I booted up Oblivion, and fast traveled to Cheydinhall, where I would walk, weapon raised to decrease speed and allow the game to load things better, to Bruma.
I would then tally up the amount of hiccups I encountered. A hiccup is a noticeable clink in the game's chainmail, no matter how minor. It has to be noticeable. It includes, framerate dips, pop in, stutters and glitches. From minor to major, all of these were noticeable, and I let around 4 go because they may not have been noticeable to everyone.
I counted 32 hiccups in performance walking from Cheydinhall to Bruma.
I was expecting around that number. Most of these hiccups were EXTREME pop in at close distances and stutters that lasted about a milisecond. and by stutters I mean pauses. Framerate dips are included in there, and usually prelude stutters. I encountered one glitch among those 32, which was a rock floating outside of the hillside it was supposed to be attached to.
I then put in Fallout 3. This time I walked from the RobCo facilities to Hallowed Moors Cemetery. I had to be relatively harder on Fallout 3, because to be honest hiccups are far harder to notice. I encountered 9 hiccups. This high a number actually surprised me because I rarely notice so many when I play, but I was actively looking for them this time, and most of them are pretty forgiving. 6 of them were pop in, but they were at a very far distance from me, and relatively confined to popping in textures, not entire stuctures and pieces of nature like Oblivion did, and the fact that it occurs far from you and generally out of your field of focus, its easy to miss. I encountered 2 stutters though. They were not preluded by framerate dips however, and lasted less than Oblivion's, though some may not be able to perceive it that way. The final hiccup I encountered was actually a common glitch in the game, a bandit raider was sliding across the landscape while shooting at me, instead of walking. The game's UI and Slow mo kills actually work well combined with the huge game world. I can get in and out of them without lag or any framerate dips when I get back to the gameplay environment. Still, I am disappointed that I found 9. I guess I remember the game holding up better in the past.
So basically, if Skyrim can beat Fallout 3, I will be INCREDIBLY happy, but if its anything like Oblivion......32 is just unacceptable for such a deep game world that focuses on immersion. That's borderline a broken game. I won't be buying it. Guess I have to wait and see....
