steam is a distributing platform a basic form of DRM, its a digital store, so steam has not much to say in terms of the actualy game
and to be honest im have lots of problems either, but remember its an elderscrolls game, i have yet to see an actual elderscroll game WITHOUT bugs, especially on release day/week
There are some workaround for some problems, and Basic Graphical Error's, ie flickering, or dissapearing Props, can be related to GPU drivers, so its a 2 way road
Both morrowind, Oblivion, Fallout, Fallout3 , newvegas all suffered from these problems, that can show that the engine itself, capable of showing some cool stuff isnt to reliable
The coding is weird on this engine, and by the use of Havok for physics, its a cpu hog aswell, im not a fan of havok at all, maybe some highly modded version yes , but in his relative basic From its abismal
