Are you having issues playing on high/ultra? I play the game on high with my machine (i5-3550, 16GB RAM, Radeon 7950), but I am pretty sure we do push things harder than BF4 did. Ultra probably could use optimizations, but to be honest if it were up to me it'd not be as big of a priority given I think the game still looks absolutely stunning on high and there's more serious stuff to look at in the short term.
If you're still having serious performance issues with good hardware below high then it's something that would be more likely considered sooner.
So in other terms, game looks fine on console, so optimizing for Ultra and fade touched for PC is not a big deal... OK. I play the game on Ultra with fade touched texture but I had to disable MSAA and force FXAA via Nvidia pannel to have some decent FPS (45-60) : but I have to admit my computer rig is quite good (i7 4790 OC 4,3ghz // Nvidia GTX TITAN OC (clockspeed 1200) // 16gb RAM DDR3 Corsair).
Most of the problems comes from origin on PC. Deactivate origin in game goes a long way. Also, MSAA is the worst AA method ever. Why not supporting FXAA or TXAA ? Some zones IG are just horribly optimized but I reckon that's an engine issue at this point.
Just as a note since some people I think think I'm some PR rep or "PIO" or whatever. I'm a dev that worked on this game for 3 years, so when I respond it's "a member of the staff" that's responding. In fact, the last 1.5 years I was on the combat team as a QA embed and in fact Tactical Camera was even one of the systems I supported (set phasers to stun). I was the one that signed off on the system from a QA perspective across all 5 platforms including both M&KB and controller support for the PC.
While I'm technical quality assurance (I do more system based testing, so I make sure the system itself is working as expected and to specification, I don't play through the game consistently or anything like that), I did help organize content QA (the ones that play through the content more consistently and systematically) to play through the game entirely through Tac Cam. Our goal was to actually let the game be playable in its entirety in Tactical Camera mode, but those playthroughs saw, frankly, really bizarre (and often fatal) issues under a wide variety of disconnected circumstances relating to looting, transitions/triggers, as well as interacting. Some of them we had to fix (transitions/triggers) because we definitely wanted players to be able to enter Tactical Camera at their convenience (very useful for starting fights) rather than restrict it to the player being in combat. Others were complicated and erratic enough fixes that they ended up disabled.
Thanks for taking the time to engage in this discussion. Although your intentions are good, this kind of answer shows clearly that PC players have been fooled since the begining of this project.
I'm willing to bet that you've never really used it as it is (its just not usable combined to the crappy AI and lack of options for companions), and moreover, that you didn't even went back to DA:O to see how it was done. I can understand that your crappy Frostbite engine, built for FPS, cannot support this kind of features fully, but UNDERSTAND that for many PC players, tac cam was THE UNIQUE SELLING POINT for this game ! Even more after all this communication BS destined to PC players that BW did.
SO yeah, you can apologize and try to explain however you want, but some of us don't buy you're PR, cause well, we actually work in PR 
I do have a preference to the controller for DAI, but I think it's important to acknowledge that throughout much of development I was supporting 5 different platforms, 4 of which required me to use the controller. It's what I'm most experienced with. But it also comes down to what, I think, are different things that we demand from PC gaming.
Well that says it all... Is there ANY ONE in your team that had preference for KBDM ? Anyone that actually worked and tested KBDM instead of just saying : "well, if it doesn't work, they'll plug a controller and will be happy". I'm puzzled by the lack of profesionalism this shows.
Cause as I understand what you said, basically there were 4 platforms that were gonna play with controller, only one with KBDM so well, it was not a priority as ALL OF US at BW were playing with controller ANYWAY !
Well done 
I'm naturally a WASD player with M&KB anyways, so that adjustment "made sense" for me. I'd like to see wider loot radius (especially since jump and interact are different buttons on M&KB and won't conflict), and I think remapping mouse controls (as well as Tactical Camera controls) would probably help me put the control scheme in a way that requires the least amount of adjustment. That said, the way the controls stand now I don't think they'd impact my own enjoyment of the game very much beyond the short term adjustments.
So none of these issues you're stating here and now, one week after launch, has ever been identified during testing phase ? Again, did anyone tested your game without a controller ? oO
- Loot radius should be GREATLY improved. Or make it so the character move to loot...
- Add some freaking toggle to see ressource nodes instead of having to spam SEARCH endlessly (have you check how much of each ressources you need to max out every thing ?! its insane ! I feel this game is only pressing SEARCH to farm ressources !)
And if you feel that controls will not impact much, you've clearly not played on harder difficulties.
I'm trully sorry If I sound aggressive, don't take it personnaly. But lastly BW has made some clear points on where they are going, and as a PC player, I can't but feel that we'll never have a good game from you ever again.
Your focus is clearly on consoles, everything you've said and done to the game showed it.
From the look of things, we can't hope for much changes and this saddens me a lot.
