Maphesta:
Even if this doesn't help everyone with a similar problem, it will likely help some people, and for the rest it could a least give them an idea of how to try to tweak the graphics settings for their particular system/situation.


JokerSF:
Many games, and other programs, have to have their settings adjusted to work optimally. Even if there are problems with the game itself, some case are due to system problems or settings.
Many bugs that can not be reproduced in-house require user feedback to be able to identify and fix.
Changing/adding features or game balancing doesn't necessarily detract from bug fixing. A programmer focusing on AI or UI may not have the knowledge or background to track down or fix problems or conflicts with the game engine, and even if they did, it would take some time to become familiar enough with the code to be able to do anything productive.


Uzeer;
The forum wasn't set up as the official / primary support mechanism. Larian has posted today in the loading screen problem topic, so it isn't dead, either.
More official participation would be nice, but I would rather have them working on fixes than posting about them.
