I finally set up my VR equipment again (since I'm testing it before we take it to my wife's Christmas party) and decided to give BoX a go in its current implementation. I had tried it before when it was first integrated into the program in its earliest basic state and wasn't impressed. Head tracking was bad and jerky, frames weren't great, etc., etc. I can very easily say that BoX VR is so far the best VR flight sim I've tried. It's incredible.
I've got everything pretty much maxed out in BoX and flipping to VR I didn't change a thing. It still was rock solid. I dropped a few frames near the ground, but the system seemed to drop frames in just fine to keep things from getting nauseous. Taking a Spitfire in BoX through the clouds after a bunch of 109s and then over the Kuban hills and rivers to the coast was simply jaw dropping.
It beats DCS easily for contact spotting, viewing the indicators, etc. The fact that there's a game to play in there as well really helps.
Probably the only thing now that would keep me from switching to VR is the chair/neck thing. I seriously need a chair that is bolted to the floor and includes straps. Without those, checking six with the headset on is very straining. Flying with SA becomes a workout.
Seriously though, if you'd tried VR and found it lacking BoX really did make it work well. If you don't have a headset yet, I might say wait until the next gen versions with better res. If you do have one sitting at home unplugged after getting bored with it, and you never tried BoX (or tried it early on), I'd plug it in again and check it out.
