Yea I figured it was a long time. I was trying to see how long I could play for before feeling some kind of motion sickness because this is my first VR system. I found that it has a lot to do with the game, I tried Orbus for 15 minutes and that did me in for the whole day but nearly 3 hours on Boneworks didn't bother me at all.
I played for a while again last night. The internal fan is working but it still got extremely hot. I put a fan in the room pointed at me and that make a noticeable difference but it still got uncomfortable after about an hour. I played The Lab and struggled to get the bow to work right. The hmd loses my firing hand when I would draw the arrow all the way back on the bow. Then I tried Pavlov again and couldn't get any of the long guns to cooperate with me. It's impossible to play a shooter with that kind of handicap and a big reason I wanted VR was shooters. I'm leaning heavily toward returning this thing and the new faceplates coming out are barely worth considering. I'm already into the Cosmos for 700, after I buy the new stuff I'll close to 1000, and I don't really like those wand things from the older vive so I'll want to buy Index controllers... It's just an unnecessary money pit. When production is caught up with the demand for the Index why wouldn't somebody just get that instead of the Cosmos and all the extra crap you need just to play games without the issues it comes with? I was happy at first but after playing with it for a while I'm feeling pretty ripped off and this left a really bad taste for being my first VR.
