Hello Unigine :D

last month I asked the problem but we still didn’t find the way

 

To solve this problem,

we used AppVive.dll into Varjo VR-3 & XR-3 (not AppVarjo.dll)

but we still have delay problem

 

I want to know is :

Why the delay problem occur and wonder how to make it better

Thank you!

 

our environment :

    i9-9900k

    RTX-3090

    Used dll (image file : AppVarjo.dll & AppVive.dll)

Hard to understand what's going on.

If you don't have any lags with default AppVarjo plugin it would mean that after rebuilding plugin it's not working as intended.

In 2.11 SDK we used following environment to build this plugin:

• Varjo SDK 1.3.x (Latest available from June, 2019)
• Microsoft Visual Studio 2015 (19.0.24215.1)
• Windows SDK: 10.0.18363

You can try to rebuild plugin using this environment. Also, you need to remove all your changes in AppVarjo (if any) to do some clean tests.

Also, I can see that you are using your own LeapMotion implementation, so it's impossible to predict how your code will work.

If you can provide a small test for reproduction with step-by-step instruction, we can probably try to reproduce this first on our side.

Thanks!
