Has anyone else seen continuous micro-stuttering, not just in cutscenes? I didn't have time to conclusively explore every possible angle, but the short of it is:

 

Core i7 3.5ghz + Radeon 7870. The framerate was fine (never below 30, is usually 40+) at 1080p Ultra all around + Fade Touched. When walking everything looked great, and when turning everything was smooth too. BUT, when I turned AND walked at the same time I had micro-stuttering, sometimes very badly, without any appreciable frame-rate reduction (latest drivers, tested with both DX11 and Mantle. Mantle was worse). If you remember the micro-stuttering problems Fallout 3 had, even on systems performing perfectly well, it's kind of like that. With Fallout it was eventually fixed by modders if I remember correctly. Nothing I tried seemed to fix it. Vsync had no effect (maybe a tiny bit better with it off). The effect is less noticeable as I increased frame-rate, but never went away (and shouldn't be happening anyway). Running the screen refresh rate at 120 instead of 60 also seems to help a bit, but why that should be is a mystery. That might fix tearing IF I was running without vsync and more than 60fps, but shouldn't have any effect on micro-stutters at all. I did of course try multiple settings, but couldn't find any magic bullet.

 

Anyway, it's been hard to find info about that because all the micro-stuttering threads I can find point to specific problems with the cut-scenes.

 

As a side note, switching to a 120hz refresh rate completely fixed all cut-scene stuttering for me. No idea why.

 

Any ideas?

 

EDIT: This turns out to have been caused by that always useless setting, the (!ARGH!) Mouse Smoothing feature! Contrary to what one would expect, the mouse smoothing slider also appears to be "backwards". I would expect leftmost to be "off" and rightmost to be "full". However, in DAI sliding the control to the left makes mouse movement slower (which, in most games, means you are increasing the "smoothing"), and adds increasing amounts of stutter into a scene. Sliding it to the right makes the mouse movement more precise and faster (just adjust the overall mouse sensitivity to obtain your desired responsiveness), and has the added benefit of completely eliminating the stutter I was experiencing.

Are you running FRAPS? because I had a rather frequent stutter visual/audio. Turned off FRAPS and the game runs like a dream, sadly that now means I cant check my fps but oh well.

 

Give it go, I was stunned that was all it was for me. I was getting ready to get medieval on my hardware etc and all that boring stuff

I have ATI cards in Crossfire, 6990m's specifically. I experienced similar issues, but being slightly older cards, they don't utilize Mantle. All my problems with the game went away the minute I shut down my second card. Everything is pretty much fine now (framerates went up and the stuttering crap went away), and I can still run everything on high/ultra (except tessellation and shadows, which I keep on low and medium respectively) in 1920 x 1080. It looks great, regardless, and I am pretty happy with it perfomance-wise (well, they DO need to fix the crashing/freezing bugs, and I'd appreciate it if they got things working for people with dual-card setups).

 

EDIT: I don't know if the 7870s even use Mantle - haven't updated my drivers in a while, so I don't remember all the notes about which families take advantage of it. Might try turning down the tessellation like I have and maybe shadows. Oh right, I forgot that I had vegetation on medium (I try to keep the draw distances non-insane, and anyway, everything still looks great).

I added an edit to the original post with the solution (at least for me). Hope this helps a few others with similar problems.

OMG I never would have thought of that and I wondered the whole time why 60fps seemed so sluggish to me. Thank you, now my mouse is properly responsive again.

Thanks so much for this!!

Thank you so much for finding this out, Skeevley! I've added your fix to the collection for everyone to see: http://forum.bioware...e-pc-version/!

Wow. Applying this "fix" (bumping Mouse Smoothing all the way to the right) appears to have completely removed cutscene stutter for me. Cutscenes still play at 30 fps (I'm not using the 60 fps command line unlock), but it's a smooth 30 fps now, as it should be.

 

Note that I'm actually playing with a CONTROLLER, so I wasn't expecting this to really do anything, but there you go. Bioware should really look into this, mouse sensitivity/acceleration settings affecting performance/stutter is all kinds of messed up.

 

Bumping for visibility.

open console and enter following command:

PerfOverlay.DrawFps 1

edity: also changed the mouse smoothing setting.. lets see what happens. This solution looks so ridiculously simple though I don't have continuous microstutter, so I doubt it does much.
