Some people say 'default' is for 512mb+ cards, but nobody from BIS or support has said this, people are guessing - people shouldn't have to guess, there should be guidance.
If the manual said 'For GFX cards with 1025MB RAM or more, select default', as a user, I'd know what to do. I would be able to tweak my settings as I know what they did. Nobody knows how to use the video memory setting, that's why there's a thread 7700 people have looked at as they don't get it either.
Quality settings are entirely different of course as that depends on the whole system configuration.
Some of the details support offered were ambiguous, I sought to resolve this ambiguity. There are threads with several thousand views because people don't understand these settings. I am trying to help them understand by getting the official statement around these settings.
Personally i have tried tons of settings, turning off PhysX, VSync etc. etc, tried all the command line stuff and honestly it doesn't give or take on my system.
Only thing i found weird and working is to NOT set my video settings too low, meaning that if i set options to high/highest i get much better performance than with settings on normal/low!
Also noticed a performance boost with postprocess effects off, this also gives a crystal clear view instead of being annoyingly blurry!
the devs don't know their own engine

The video memory setting systems mostly a mystery to everyone though (some people think very high is for 2GB GFX cards, some people think very high is for 512MB GFX CARDS) - I tried to uncover this mystery... but alas... I guess we'll have to keep on guessing.
I think the devs certainly do know their own engine, just that no devs with the knowledge of that part of the engine have shared that knowledge yet...
Honestly I'd be more happy if they worked on a patch that will solve performance issues rather than having them babysit the forum for people who try workarounds for the same issues.
Don't get me wrong I'd try anything that will make the game smooth (and btw that doesn't necessarily mean high FPS, there is a difference). But in the end I want a patch that fixes it instead of 99 opinions about parameters in game and in gfx drivers.

Not sure what you mean, I'm not saying that devs should not read the forums.
But if you rather have them put all their energy on answering questions on parameters that might not even make any difference than working on the patch. Then I guess we will never see a patch.
