SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components


On a small PC with only Intel HD Graphics 4600 the DirectX rendering is not supported by SciChart. Thats fine but it should use the fallback render surface.

  RenderPriority ="Low"
  s:VisualXcceleratorEngine.FallbackType="{x:Type s:HighQualityRenderSurface}"

I got this exception:

    System.Exception: Your GPU is blacklisted for use by the Visual Xccelerator Engine! There are several reasons why a GPU could belong to the blacklist. For example, low computation capabilities of the GPU could cause Timeout Detection and Recovery of Graphics Adapter Drivers by the OS, resulting in crashing the application.

But it should use HighQualityRenderSurface without any exception.

Hi Tobias

Try first of all using our nightly build 6.2.1, as we fixed an issue related to incorrect GPU Blacklisting in that nightly build which affected some dual-GPU pcs.

Secondly, try setting the properties s:VisualXcceleratorEngine.FallbackType and s:VisualXcceleratorEngine.DowngradeWithoutException before the IsEnabled. I have a suspicion that IsEnabledChanged is fired first and these properties don’t exist.

Best regards,
