Does Resident Evil 7 require a VR headset?
Solution 1:
On PC you certainly don't need the VR headset (speaking mostly from experience, but you can find many streamers/speedrunners that run the game without a VR headset). I went over to twitch and did find some streams that were on PS4 and the streamer did not have a headset on (for instance, here). Furthermore, the PS4 store itself does not sell a VR version of the game, just the game itself as VR compatible (seen here).
