We are starting to investigate a problem we have where our headsets start crashing after about 45 minutes of play. It started happening at the same time we migrated to vive focus 3. We aren't completely sure if it is related to the vive focus 3 at this point but I was wondering if anyone ever heard of something similar or had a similar problem?
Here are our current Steps to reproduce :
connect to the game
Walk with the headset on for between 45 min to 1h
Observed behavior :
The headset crash between the 45min to 1h mark.
The tracking suddenly becomes unstable, the screen goes black, then blue (because it doesn't have tracking), then when it regains tracking the player finds themself in the vive menu instead of the game.
Additional information :
This crash only happens if the headsets are in movement for the duration. Headsets in standby are not crashing even for longer durations.
The fact the screen goes black and blue because the headset doesn't have tracking makes us suspect it is the headset that crashes and not the game.
Furthermore, we have installed bugsnag (an android app crash logger) into our game and it is not capturing any game crash when this happens (we validated it does capture normal game crashes), reinforcing the hypothesis the headset is crashing and not the game.
We are developing on Unreal 4.27
Thanks for your help!^^
Hey everyone! We are developing a shared space high action multiplayer game. Because of this, it is very important that our users get notified as soon as possible when they or another player loses tracking to avoid accidents. To test how fast a player would get notified someone lost tracking we used the "Get Device Error State" node, then hid the headset's cameras and counter how long it took to return true. We measured it takes 7 seconds on average to get the notification, which is way too long for our use case. Is there a faster way to know if a user lost tracking? We are hoping to get below 1 sec between the time the cameras are obscured and the moment he headset notifies the game engine that tracking has been lost. Thanks in advance! .G
