The Stillness illness...

I've gotten sick with certain content (sorry TF2) but it really depends. Most of the time now I don't have any issues. I usually only play for short periods, maybe 5 or 10 minutes at a time. It's recommended to take frequent breaks and not try any marathons. Also, be sure to read the Best Practice guide to make sure you are authoring the content correctly.

Hoping DK2 brings enough improvements to make sickness much rarer. At the moment about 40% of the demos leave me feeling a cold sweat and the odd belly grumble, and about 5% leave me feeling dizzy, hot flushing and like im gonna throw up (although I never have yet).

The other 60% I can play for hours without any issue.

Making your own content is more likely to get you sick, especially your first time while you learn how to contruct the environments, scaling etc. The more you can do from knowledge before you 'go in' the better. :geek:

I think you need 300 fps on the DK1. Try to disable all funky stuff, any sync and you should be fine.

You definitely don't 'need' 300 fps... Getting over 70 is fine for most people.

As I said HL2 runs at 90 fps and it turns me inside out. It's individual, but if it makes more than 5% sick, you might aswell cancel the project. Anyhow it's just a recommendation, try it yourself and you will see! Then you can go back to 70 fps.

This is the problem right here; employee, conference, expo and show sessions only last for 15 minutes max... that's not how we want to play!?

I suppose some people are simply less tolerant to that sort of thing. I've put dozens of people through a wide variety of demo's and certainly haven't seen anywhere near 300 fps as a standard. Below 60 makes most people unhappy, below 40 is very uncomfortable but the very few people that did feel bad to their stomach after playing was due to the 1) type of demo or 2) poor implementation, rather than a low fps.

Again, this is from dozens of people playing a lot of different demos on my station rather than simply my own personal feelings.

I read somewhere how VR is so immersive that you would sweat under a virtual desert sun and get a cold freeze when visiting a winter scenario. Today I think it was all due to the testers feeling that same cold sweat :D
I get regularly myself.
Edit:
Idea! Only doing desert and winter games and sell cold sweat as a feature!

Yes, but for how long? Ofcourse you need to render 300 real (with fresh sensor data) frames per second, if you manage that, you can't be doing it wrong.

I challenge anyone to play any demo that's out there now for one hour and not feel bad after!

Most people sampled between 15 - 30 minutes.

Did none feel bad afterwards? I mean in the 24 hours that followed?

The reason most feel bad by HL2 is that there is no other VR demo/game that has more than 15-30 minutes worth of content...
