It was the only Mod installed at the time of testing.
I have not updated my Graphics drivers lately. (New graphics card coming in a week or so).
Clarification: Yes.
Using Open Track.
I have not tried it without head tracking. Can't go back to padlocking and "Hat View"
I'm not uninstalling all of the mods I've added since (that do work) to get this one so that it might work.
I know I read a fix for this somewhere, but I can't find the thread anymore.
