They ran an unoptimized version of the game at max detail on below minimum specs PCs at that expo (CPU and GPU were fine, but RAM was below specs). Stuttering or not, it was playable enough to be shown that way in a gaming expo.
Just in case someone got confused, let me point out the important bits again:
Unoptimized version.
At full detail.
On a below minimum specs PC.
I guess that if the PCs had 3-4GB or RAM instead of just 2GB, it wouldn't need to buffer-read from the hard disk all the time and would be smooth enough. I also guess that after 2-3 months of pre-release debugging and optimization, the version we will have in our hands will be somewhat better still.
You know, it's amazing how much cause for alarm can be avoided if we take the time to put 2 and 2 together.
And while i can see that newcomers to the forum would not know about certain pieces of information to deduce all that, i can't understand why old-timers who post here multiple times every day would miss the same info.
