Having a wide enough Field of View is important to avoid getting dizzy. Running a DirectVR scan during gameplay can help this if available. Otherwise you’ll need to find ways to greatly increase FOV in a games settings.
Battlefront 2 has FOV slider in the video options. For fullVR you generally want it somewhere between 100-130.
If you are still having trouble getting used to the headtracking of FullVR mode, maybe try out the cinema modes from the Delete key menu to see how that feels. You can adjust the size of the screen, and also the strength of the 3D depth and still get an immersive experience. There are also sliders for sharpness and brightness, this can help make it less blurry.
If you want an example of this, search my name on the Cloud Profiles of vorpX config app and import my SWBF2 profile (not the beta one). In game set FOV around 95 and see if it feels ok.
