For 1) Which mod are you using? try the Immersive First Person View rather than enhanced?
Can’t say for the rest I used good old mouse and keyboard…
I guess you fixed it but for anyone else…
In the FirstPersonPlugin.txt in the \steamapps\common\Skyrim\Data\SKSE\ folder
!set fPositionOffsetDepth -15
and
+set bHideHelmet true
Ah ok. I tried vanilla but got the same issue.
However… it actually seems like it happens out of VR as well (though it’s always been fine on my system) so there is already fix :) Tweaking the SkyrimPref.ini or by a mod to disable the underwater effects.
This worked for me…
