Most experiences are very shaky in the Oculus Rift.

With shaky I mean lag when moving my head.

These scenes are very shaky for me

• Tron Grid Prime Millenium (https://atlas.sansar.com/experiences/mijekamunro/tron-grid-prime-millennium)
• Sky Naturae Virtualis (https://atlas.sansar.com/experiences/alexbader/skye-naturae-virtualis)
• Rodenberry Nexus (https://atlas.sansar.com/experiences/roddenberryentertainment/roddenberry-nexus)
• Coloseum for Sansar Top 5 (https://atlas.sansar.com/experiences/sansar-studios/colosseum-remix)

An experience that does not have this issue

• Scurry Waters (https://atlas.sansar.com/experiences/fullspectrum/scurry-waters)

I'm running:
Processor: Intel Core i-6600K CPU @ 3.50Ghz
RAM: 16GB
VGA: NVIDIA GeForce GTX 1070

Does anyone else have these issues in VR?

Thanks!

  I had the same issue in my own build and after tweaking and removing lights I managed to solve the issue in my scene. I still see some lag on objects borders.

  At the moment I think it has to do with lighting. Not the amount of lights because I have more lights now than when the issue was apparent the most.

  Anyhow, I'm still wondering if anyone else is seeing this.

  Oh and BTW: I don't see these kinds of issues in other VR applications but I re-installed my VGA drivers just in case. Did not change much.

  I did not have the amount of lights in my scene as in this video so I'm not sure my scene was suffering of bad lighting settings but this is a nice video explaining light in Sansar. https://youtu.be/sXQr1wLf4to

  Having it again in my scene but it starts after a while. Frame rate in desktop mode is 100 frames. The Sansar client is also quitting every once in a while. I'm assuming it is a bug. Would be nice to have confirmation. I have spend hours at tweaking lights already.

  one thing that caught me out with similar problems for ages (although a vive) was that I had my monitors tilted too much diagonally towards the floor. I tilted them back up nearly just pointing towards each other and it fixed a lot of lag problems - may help. If not other problems have been caused by objects over 200k triangles with the wrong orientation settings (esp dynamic), very small dynamic objects (where volume was too small after resizing a model too big on import). I also recently lost a whole experience because it was over 90 million prims in total.  BUT I am only running a HP Omen laptop with a GTX1050, Intel i5, 7th Gen. Sky Naturae works fine so it's certainly not your system.

  Thanks for your reply Charmarley. I have checked some of your tips. I'm adding the info just in case it is of any help.

  Am I right assuming that with your "monitors" you are referring to your Lighthouse sensors? I don't see this kind of lag in other games in VR. Some of them even render out in VR and my three displays at the same time. My Oculus sensors are fixed. If there would be an issue with them I would expect issues in other VR games.

  The most complex objects in my scene have about 8K of triangles. I'm not sure what you mean with "wrong orientation settings (esp dynamic)".

  I now have some resized models (enlarged to 1.5) but I noticed the lag before I added this objects (which are clones from the same object, BTW).

  My complete scene has now 349K of prisms. 666 of draws. I don't think this is very much.

  Yesterday I visited Tron Grid Prime Millenium (https://atlas.sansar.com/experiences/mijekamunro/tron-grid-prime-millennium) again. This time I was the only one there and I walked around for a while without issues.

  In my own build I was able to walk around for about 5 minutes before lag started. I left VR to desktop mode and went back into VR to see the issues gone again.

  To make this thread complete I think I should should mention I am using Reflex4 scrips which I love, BTW.

  One of the people from LL advised to describe what I mean with "shakey" and " lag". Not an easy task but I'll try.

  When I turn my head, it looks like my system is having problems rendering the view on time which results in me seeing my objects double for a split second. This is especially visible with light emitting objects.

  The same person mentioned he does not have this issue on his Rift so it's probably my system. As I mentioned above it is a bit strange that Sansar seems to be the only application showing this issue... that I know of.
