We are pleased to announce that the SciChart WPF v6.2.0, build 13254has now been released! This update includes a number of bug fixes reported by users since version 6.1.1. This release is a drop-in replacement for 6.x and it is recommended for all users to update.
What’s New in SciChart v6.2.0?
1. Addressed the Startup time of SciChart WPF.
Version 6.2.0 will now be up to 28x faster to initialize and show the first chart than v6.1.x. This improvement will be seen immediately and no changes to your code are required.
The time to initialise the first chart was due to initialisation of native libraries, licensing and the 3D engine. This has been significantly streamlined and
2. Addressed compatibility with older GPUs and multi-GPU PCs.
We’ve introduced a compatibility check on engine startup, and for multi-GPU PCs, SciChart will now choose the best available GPU. This solves a lot of problems and will improve performance on many of our users computers. Check the Visual Studio Output window after startup as we now log the compatibility check there!
We have identified Intel HD 4000 Series GPUs as having not enough Video RAM (VRAM) or features to correctly use SciChart’s Visual Xccelerator Engine in DirectX11 mode. We have added a check to downgrade to DirectX9 mode which uses less VRAM, or to choose a better GPU where one is available. This was a huge piece of work by our team which involved testing on multiple combinations of graphics hardware to ensure maximum stability and performance on end-user computers.
3. Improved the placement of labels in Perspective and Orthogonal 3D Charts
Label Placement has now been improved so that labels no longer overlap. This was a feature-request on our feedback portal and we’re pleased to announce its been delivered!
4. Created a Vital Signs Monitor demo
We’ve created a Vital Signs Monitor demo for SciChart WPF, to mirror the demo we have created for our iOS & Android charts. This can be seen in the short video below.
