My VR unity experience keeps crashing with a ntdll.dll error
Hey everyone,
I'm working on a VR social world called Convrge where people can meet up and hang out with others. I thought I would lead with this since our build is public so if anyone is able to reproduce my error and knows a solution please let me know! Download is at http://www.convrge.co
Our latest build runs fine on my Macbook pro and most every other mac or win rig I've loaded it onto or that our users have. This seems to be a very niche problem / something specific to my machine. I can stay in the experience for about 5 - 10 mins on average before being kicked and seeing the below ntdll.dll error message. Sometimes it's instant as soon as I load the world, sometimes it takes 15 mins, there doesn't seem to be a pattern:

I've seen people include their dxdiag.txt file for reports like this so here's mine (attached)
And here's the laptop itself: http://www.amazon.com/G750JM-DS71-17-3- ... B00IKF2H12
At one point I thought this error was being caused by other clients connecting to the game, but I've been testing it tonight with no one but myself in the world and the error still occurs. I've tried rolling back my Nvidia drivers one version at a time for about 4 versions with no success. I'm back on the latest Nvidia drivers now. I've installed all available win 8.1 updates. Unity is version 4.6.1 due to a plugin were using that isn't supported on any further versions.
This bug seems to occur randomly and not associated with any particular part of the world, other users, character movement, etc.
Please let me know if you need any more info. We're heading to GDC in two days and would really like to show our stuff on this machine without it crashing all the time :(
Thanks so much!

- Issue is still occurring and now happening on other users machines. Mostly seems to be people with win 8.1 and Nvidia cards.
Any ideas please? This is causing 5 - 6 of us to crash constantly and we don't know what we can do to fix it.
Thanks! - Can you upload the "output_log.txt" from the game's *_Data" folder (from one of the crashed runs)?

Thanks.
Here ya go. I've removed everything except the crash on the recommendation of our lead programmer since he says this is all that should be required to diagnose the problem and the other logs contained sensitive information about our server IPs and other things we don't want to share publicly. If some of that stuff is important please let me know and maybe I can email or PM you the full log privately?
Thanks so much!- Had about 6 people having this issue last night. Seemed like most of them were on win 8.1 with Nvidia cards. Any update on what we might do about these crashes?
Also I'll add that the crashes start slowly for most people and then escalate in frequency, which makes me think it might be a memory leak issue? - Any update on this? I provided the crash log 3 weeks ago and haven't heard from anyone :(
We still continue to have a lot of our windows 8.1 users experience this crash daily. - Over a month since my initial post on this issue, I've provided everything that was asked for, and we continue to have almost all of our win 8.1 users experience this crash on a regular basis. Can I please get some sort of response or assurance that this is being looked into?
Thank you - I'll see if anyone here knows more. Sorry for the delay.

Any luck? We're starting to have reviews like this pop up on our Share listing haha:
"Really really cool except if you have Windows 8.1 and an nVidia GPU.... don't even bother. Massive gamebreaking bug that crashes the program every minute or so... Devs are aware of the bug, so just wait until they've fixed it."
Thanks!
