I had to lower some of the in game visual setting, to make it run smooth in VR.
One thing I can't seem to do in VR is zoom in with the camera. Not yet.
Other than that, most everything else works that would work out of VR.
I did try to use both the VR controllers, and an X-Box controller, but I found I prefer to use mouse and keyboard with the VR headset on. Plus, some of the keyboard keys does not seem to be linked to any controller button. Such as crouch or run. So for now keyboard it is.
The mouse makes for much more controlled turning when needing to walk across planks, and aim the camera at a target.
Once all is set up, I feel like I am in the game itself. I can look all around the place naturally, just by turning my head. The mouse controls my forward movent and camera, wile moving my head lets me see everything in view.
One other prob I have, is remembering all of the keyboard button positions wile in VR. I may have to give my Razer Tartarus keypad a try with the mouse, instead of a keyboard. That should help fix my keyboard issue wile my headset is on.
For the most part, aside from the visuals not as sharp as viewing it on a 2D screen, it's vastly more immersive in VR.
Seeing UEVR is free, and if one has a PC VR headset, I do recommend giving it a try.
