My buddy got a deal on a full sim racing setup on Craigslist and holy shit the difference between tv and vr headset is night and day. It's very immersive.

The one time I tried it for war thunder sim sucked because the resolution was too low to identify friend from foe and made it unplayable.

I don't own a vr headset, just borrowed them a few times because otherwise its totally not worth it.

For sim applications, it is game changing though.
