Everything in that list is FUD, not to mention that it originated from some random user on a very insignificant discussion board who claimed to be some sort of supervisor in a company which supposedly bought hundreds of Fallout 3 copies for testing purposes and they came up with those "conclusions" from their expertise after hours of testing. And most of the best modders the community has all verified those claims, they also tested, and they all concluded that it was all FUD and false information, the only thing that is true is that the GameBryo engine is getting old, it wasn't tested by Bethesda on all possible hardware combinations and it's very sensible to third party codecs especially regarding audio, that's it, no more and no less. I myself don't like GameBryo, it's very 2002'ish (Morrowind period, it hasn't changed much ever since), but that's just my perception, but that list of mishaps above, it's FUD, it has been proven to be so in the community a long time ago, and whoever that guy is whose the originator of all those lies probably had random crashes and was frustrated enough to invent that little story of his. I spent enough time myself with the GECK and trying different mods and making one myself (one for F3, one for Oblivion), I've spent enough time on the Beth's forums and I know enough of the best modders out there to know as well that they know what they're doing, what they're talking about, and some of them are certainly (perhaps arguably) better than some of Beth's guys themselves.
With all that said, seeing the situation objectively, as much as I don't like it, the game does run fine for a lot of people out there and I'm surely believing them, I for one am always crashing in all Beth's games, from Morrowind to Fallout 3, it has never been stable and I've had exactly three completely different system builds since Morrowind came out, I went through hundreds of different drivers ever since, nothing ever worked even with just a fresh OS + Drivers + Game install and nothing else. The thing is, as mentioned earlier, it is well known by now that GameBryo is very sensible to many hardware combinations and certain software and codecs as well, it's usually (if not always) up to the PC user(s) to figure out what's wrong with a very simple and ages-old elimination process, removing third party stuff, mods, beta drivers, adjusting the game's configurations, etc, in the end it may still never work, it's just the way it is for lots of people, I accepted it, but it forced me to uninstall all those games (Beth's games), it's a shame, because I like them, despite their old feel, the game-play is generally better than pretty much most of the other games that we keep getting lately, and that I'm ready to recognize it, but that damn dinosaur of an engine it's running on needs to be wiped out from the face of this digital world once and for all, if Bethesda dares using it again for Elder Scrolls V it shall be MY biggest disappointment in video gaming, unless Diablo 3 gets canceled.
