One of our users have a setup where they have a VM with very little graphics capabilities and it appears that when we open one of our SciChart panels for the first time, it takes about 4 minutes for everything to populate. The next time, it only takes a couple seconds as expected. This is a bit of a long shot question, but have you ever seen such an issue on any sort of machine? I’ve attached the settings we use for the VisualXcelleratorEngine.

Thanks for any help!

    Thanks, Lex. We’ve set the fallback type to HighQualityRenderSurface and have enabled everything as the above links describe. I guess I’m wondering if there is any way find out if SciChart initializing is what’s causing this really long delay on this sort of machine. Thank you, Matthew

Hi Matthew,

Thanks for your inquiry.
We do not recommend using low-end graphics for the hardware-accelerated rendering. Please take a look at the SciChart System Requirements documentation page for more info:
https://www.scichart.com/documentation/win/current/webframe.html#SciChart%20System%20Requirements.html

You can also find basic Hardware requirements on the Visual Xccelerator Engine documentation page:
https://www.scichart.com/documentation/win/current/webframe.html#Enabling%20The%20Visual%20Xccelerator%20Engine.html

It would be better to use software rendering for such machines. Here you can find more details:
https://www.scichart.com/documentation/win/current/webframe.html#Renderer_Plugins.html

You can also prevent enabling Visual Xccelerator Engine for such configuration by blacklisting the faulty virtual graphics adapters. Please take a look at the “GPU Blacklist” section of the following article for more info:
https://www.scichart.com/documentation/win/current/webframe.html#Troubleshooting%20Visual%20Xccelerator%20Issues%20on%20low-end%20Graphics%20Adapter.html

Hope this helps.

Hi Matthew,

I have additionally discussed your inquiry with our team.
It’s expected that the first chart loading time will be longer because Visual Xccelerator Engine loads all the required resources.

However, it is possible to start Visual Xccelerator Engine asynchronously. This allows to avoid or reduce the Engine startup delay by making the Engine initialization happen when other application code is being executed.

You can find more details in the “Asynchronous Visual Xcceletator Engine Startup” section of the following documentation article:
