I've been in contact with support several times about this issue and it hasn't yet been resolved and they suggested I reach out to the forums to see if anyone else has had the issue.
Basically whenever I move the chase camera shakes violently until I stop. It happens anywhere on a whim and is getting worse and worse. Even using seethe on my fighter will trigger the shaking as long as I continue the animation.
I originally thought it was tied to my fighters run speed buff but now I do not think so.
Here is a video of the issue, it is MUCH worse now.https://drive.google.com/file/d/1-qGsCmCsRpi2YzGRkH-ZUD2YW0YmtUoA/view?usp=sharing
Drivers are up to date.
Computer is more than adequate (i7, 16 GB ram, 1080FTW).
I am on Steam if it matters.
Resetting FOV with /gfxSetDefaultFOV does not help.
I've tried setting values for /gfxSetDefaultFOV from 25 to 100 without luck.
Updating drivers did not help.
Forcing a file verify on launch did not help.
Completely uninstalling and wiping the game and reinstalling from scratch did not help.
I've tried every graphic preset from lowest to highest, does not help.
I've fiddled with post processing, FXAA, V-Sync, etc. with no success.
Zooming the camera closer or farther does not help.
Turning off screen shake does not help (it isn't an effect, it's a bug of some sort).
It *seems* worse on my lvl80 fighter than on my low level ranger.
It *seemed* to get worse over time and over levels.
Not sure what else to do w/o some technical support but it physically makes me ill after a little while. Kind of a waste of a VIP sub.
