I didn’t see a source for the statistic in the article which is a bit disappointing as I’m really interested to learn more about it. It seems pretty high but also there’s quite a lot of uncertainty built into it.
From my experience with VR I found I got sick after a long enough time but was able to get my ‘vr legs’ and have much longer sessions even on more intense games like Windlands where you swing around like Spiderman (super fun if you have the stomach for it).
The other thing to note is that for me at least it’s a spectrum. It’s not just ‘VR makes me sick’ but it depends a lot of the game or activity and there are a bunch of ways for games to try and reduce it. It does take time to get used to some of them though.
Hopefully things become better with time and more folks get to enjoy it because it’s a lot of fun in my experience.
