Is VTK.js performance dependent on the GPU and browser ? With the same app and data, it runs smoothly on a laptop with an NVIDIA GPU but lags a on an Intel integrated GPU (in Chrome). Are there simple settings or best practices——that help make performance more consistent across different machines?

The vtk-js rendering phase relies on the WebGL graphics API, which uses the hardware GPU for rendering tasks. Performance depends on the hardware.
