I repectuflly
disagree that WA are due to a lower end system.
I have a machine that plays all the Dragon Age series and one was just recently
released as well as warcraft etc.
It and nightlife are glitchy addons that were never tested properly
The excavating problem in WA has been there for a year now and how can that
be a computer problem
When push comes to shove no one knows what is causing this except for EA
and they are not saying but I do believe your observations are likely the problem
although I dont understand it all as Im not a computer techy by any means.
