I don't even know where this stuff came from. Watch, I bet there really is no problem - it's just the same entitled little brats trying to cause problems. Yeah, there are some glitches and bugs out there, but there's no reason not to be civil about it. Screaming at Bathesda and making up fake problems to make the game sound like it has more problems than it really does really doesn't help at all.
What we need are examples of the things people are claiming. We've seen vids of the lag problem, of the dragons acting up, and we have comparison screenshots to prove this "texture quality drop" a farce. Less being brats, and more actually working to help give bathesda as much info as we can - the more civil and detailed we are, the quicker these things will get fixed.
Simply labeling people 'brats' for commenting on their opinion of the game is farcical. Grow up.
You ask for video evidence, which is hard to do without
a) Having the hardware available to capture video

Spending a whole lot of time to install the game, reinstall from scratch, take pictures, patch and take more pictures.
At the end of the day the visuals have noticeably changed for me, I still enjoy the game but it is not as beautiful or immersive as it was. I doubt anything is going to change, as this was the fix Bethesda felt was necessary in order to make the PS3 game playable.
Each will make their own choice as to what to do, me? I'll continue playing my 'not so visually imprresive anymore' game and will probably still replay. I will look with envious eyes to the beauty of the PC still.
