"Makes you feel rather ill after a very short while.."

10-15 minutes and headset has to be removed due to feeling ill, is not a good result frankly. This is exactly the problem many of us saw years ago.

It's like the elephant in the room, where everyone accepts that sub 20ms is the target, but despite not even coming close, they release it anyway.

Why do you keep saying this crap when I've explained the reason several times? Maybe bold will help?

Artificial locomotion in VR games will cause motion sickness in some people.

A perfect headset will not prevent motion sickness in games like that.


The oculus rift has ATW enabled with every game compiled against sdk 1.3 which by design reduces MTP latency far below 20ms.

Both rift and vive use prediction as well so in the general case (e.g. non-erratic movement) the perceived latency will be close to if not 0.

Edit: and if you had continued watching that video for 20 seconds after the point he mentioned the nausea, instead of excitedly rushing back here to post more VR bad news, you would have heard him say "there is a comfort mode that completely solves the nausea"

If the hardware is what causes the nausea, how is a mode within the game able to solve it?

The point that you missed, SDK 1.3 was released yesterday. Games have to be recompiled and updated for it. There's no evidence they have MTP latency far below 20ms at all. <- This is the contention, only claims are made, no independent proof.

So far all the reviewers have noted feeling ill or discomfort, shaky, sweaty, and they had to take the VR headset off.

As for "comfort mode" in the game, it limits your head movement so you can't actually use it to move the view around. If you want to move, you click on arrows and the scene fades to black and back at the new PoV. That's a hack, a brutally crap one at that.

Ok, forget what I said about ATW since it's not in all games, although it shows a lack of understanding about what ATW is to think it is possible for it to have > 20ms MTP latency.

If you want to talk about claims without independent proof, please show me where ALL reviewers have had discomfort. I watched about 10 hours of Giant Bomb's stream and 2/4 said they had no issues playing a wide variety of games.

Also please show me instances of reviewers getting sick playing games rated "comfortable" by oculus.

And yes, "comfort mode" does severely limit your interactions with the world in that game. It is probably the biggest limitation of VR and it's not going away. Seated and standing 360 VR games where your virtual head moves independently of your actual head will need to use this or something similar to ensure a sickness free experience, regardless of headset latency. It's one of the main reasons I am more interested in vive's room scale games where the majority of movement is you walking around your own VR space.

.

1.3 was PUBLICLY released this week. Select game developers have had it much longer under NDA. Elite Dangerous was even updated to SDK 1.3 last week in preparation for the Rift's launch. Oculus launch titles are all 1.3 as far as I know

VR will make some people sick no matter what. Doesn't matter how much you try to make the problem to be something else.

I think one of the theories is that motion sickness provokes the nausea response because unable to reconcile the conflicting inputs, the brain's interpretation is that you must be poisoned and hallucinating and so the best thing to do is to purge your stomach to get rid of any poison you can.

VR is poison for the brain!!!
