Version 8 of DicomObjects uses DirectX rendering by default (version 11.1), which is massively faster and more flexible than GDI+ rendering, but it is possible that some very old hardware might not support DirectX, so GDI mode is maintained as a fallback.

For testing and debugging purposes, this value can be over-ridden at run-time by the "ForceDirectX or ForceGdi "registry" Word values by setting the required value to 1.

Target Platforms: .NET CLR 4.8 or higher
