Thanks so much! I will update when I start my next character. This one just killed the last dragon, and has no zones left to explore.
I figure I might as well take the time to list my game settings. I'm averaging 55-60 FPS, with the only big drop happening in Redcliffe. I don't use SweetFX, nor any other enhancing mod.
Graphics
Texture--Fade Touched
Thank you so much for taking the time to list your specifications and settings! I would however recommend switching your Texture Quality setting down to "Ultra", since there is 0 visual difference between it and "Fade Touched" and your game might actually run better as well! Either way, that's a great tweaking effort there, your game looks stunning and performs really decently! 
I've noticed that fade-touched indeed doesn't solve texture pop-in on a gtx 980, so what exactly does fade-touched even do?
Thank you for asking, that is an excellent question! Here is what Andrew Burnes, writer of the official Nvidia performance tweaking guides, had to say about this particular setting:
"It's simply a larger texture cache for GPUs with more VRAM using Ultra textures. Should mean less frequent loading of textures into memory, which may result in smoother gameplay and quicker mid-level streaming loads."

Sorry for the double post, but after experimenting earlier, it appears that the FPS workaround no longer causes the Stuck in the Fade bug after character creation. Those cutscenes look much better now. 
That is really great news then, thank you very much for reporting! Who knows what exactly the recent patches must have changed, but I'm genuinely glad to hear that DA:I is that bit more user-tweaking friendly! 
However, do you really think I should update the OP with this information, since I wouldn't want some very angry PC players coming back here to lynch me after spending whole hours in character creation only to be stuck in the Fade the second they want to start actually playing the damn thing! 
suspect I'm going to have multiple post this as I'm not sure where I might receive any help / advice:
obviously I'm unusual here, as I haven't seen anyone else mention this - but I can't stand what I take to be the games HDR / eye-adaptation effects ... in outdoor areas they come close to making me nauseous...
I'm talking about the continually changing degree of 'brightness' and colour saturation etc, as one moves / looks around.
To me at least it isn't realistic, and I find it highly distracting.
(an example: in Haven - run around and you'll suddenly find the landscape getting much darker and 'saturated' in certain areas)...
anyway, hope I'm making sense here - I've looked around at all the user.cfg tweaks etc I can find, and have played around with the in-game settings, and nothing seems to make a difference...
anyone got any advice?
Hi there and a warm welcome to the dedicated PC fixes thread! Don't worry, we're all friends here and we don't give up easily on trying to fix our favourite games! 
That being said, I think I remember noticing the effect you are referring to, but it personally didn't bother me because almost every game features "eye adaptation" effects these days. However, since there are no in-game graphics settings that control this effect to my knowledge, let's have a look at the in-game console commands instead and see which ones might help:
PostProcess.FilmicEffectsEnable - this rather obscurely named command likely controls extra visual details not accessible to regular players via the in-game graphics settings menu, so maybe by setting it to "0" it will also disable the eye adaptation effects?
PostProcess.ScreenSpaceRaytraceEnable - this command probably controls the drawing of "God rays" (i.e. light beams) when the sun is obscured by objects in the environment, such as tree branches for instance. What if disabling this effect also disables eye adaptation/dynamic HDR?
To test the result of each of the in-game console commands, load up your game in a peaceful area, press the "`" button on your keyboard (the key to the left of "1" above the WASD cluster) to open the in-game console and start typing each of these commands in turn. While typing, the in-game console will automatically bring up the full name of the command, as well as its accepted parameters - these are crucial to using the commands effectively! 
Unfortunately, I am unfamiliar with the accepted parameters for some of the more obscure commands in the list I've linked above, since I haven't personally used any of them. Feel free to experiment for yourself with them and don't worry - everything is perfectly reversible and any in-game console commands that you input also get reset once you close the game, so if anything should go terrible wrong, just close the game, restart it and everything will be alright again! 
Good luck and please report back with your findings should you find the time! Otherwise, have fun playing the game!
