I have no problems with the visuals. Hell, I still think FO3 and NV holds up just fine visually, vanilla. They're actually fantastic examples of how it's not what your engine is capable of that matters, but what you do with it. Wandering the wastelands have always been a fantastic experience because of the design style and art they've used rather than polygon count and texture resolution. I'll never complain about higher quality in those things, but nor are they the be-all and end-all of visual quality.
Sneaking through subway tunnels and slow walking through the wastelands have always felt amazing to me, because both Bethesda and Obsidian have been very good at art design, asset creation, world building and so on.
My gripes with this release has entirely been about the UI and technical aspects from being a rather shitty console port in all aspects but optimization. I expected it to be bad given the previous releases, but this was worse than expected. Like X games etc, it's something I'll probably get used to in time, but there's no way around the fact that it's terrible design.
It's really weird how some of the best games out there tends to hide underneath some terrible UIs.
@Samira: It's not so much the bugs (I've only really experienced a few, one major crash, one driver crash which may be Nvidia's fault, and a few conversation/subtitle derps) as it is the UI design and interface setup. I mean really, forced mouse acceleration, mouse smoothing, framerate lock at thirty, no FOV options in menus, every in-game interface being clearly controller focused etc etc. This is really bad porting.
Most of it's fortunately fixable if you're willing to dive through three different .inis to mess with it, but the basic UI design is just not fixable. At least not until the modders have had a lot of time working on it and maybe not even then depending on how they're built into the game.
