It isn't a problem with screen technology or processing technology or anything like that. We aren't going to "tech" our way out of this.
It is a biological problem and as such, I think the appeal of VR will always be rather niche.
Even the best selling VR headset that I found online was the Quest 2 and it "only" sold like 15M units (honestly way more than I ever expected) with everything else being considerably lower volume. Compare that to the number of Nintendo Switches sold (130M) and you start to see how small the VR market is. I am very curious to see how the Sony VR2 will end up selling. I would love to get a pair, but I think all these headsets will be short lived.
VR has been around since the 20th Century. It is still here, and the market is expanding with more options as time goes on.
I wanted to play VR games since I saw the first VR stuff in the 90s. Finally got a Valve Index set this year, and it's fuckin' awesome. For all the Quest and Vive users on here saying VR sucks - it's your gear that sucks.
Here's a list of VR games that are fuckin' awesome:
HL Alyx (as everyone already mentioned)
Into the Radius (S.T.A.L.K.E.R. in VR)
Grapple Tournament (UT2004 with grappling hooks in VR)
Dragon Fist Kung Fu (kung fu fighting in VR duh)
Blade and Sorcery (swords and sorcery)
Battle Talent (ripoff of Blade and Sorcery that is also cool)
Assetto Corsa (racing sim)
DCS World (flight sim)
Beat Saber (music chopping)
I don't know man. Feels like the whole damn field of medicine does just that. It fixes body problems with (medical) technology.
I would not at all be surprised if later we find a certain framerate or fov reduces motion sickness. Or maybe there's some device that will go over our ears to trick our equilibrium from getting confused. Or maybe really good head tracking fixes it...
I think it's more likely than not that we do "tech" our way out of it - just in some unforeseen way.
Only one way to find out, I guess. But still, a lot of this stuff comes from the high end that eventually trickles down, and I've never heard any discoveries that claim to have solved the problem. You'd think that since the military would be all over this tech, their limitless budgets would have stated they have sickness-free headsets. But in all these years, nothing.
