I've upgraded from 2018b to 2020b. But now the opening of "configuration parameters" in simulink model is much slower than 2018b. Is it normal? Or what should I tune?
Thank you very much in advance!

By default MATLAB tries 'opengl hardware' on the machine, and if some reason it detects some incompatibility with graphics drivers and it might have used the 'opengl software'.
'opengl software' is slower compared to 'opengl hardware' (as now the Graphics card are much more powerful) and hence forcing MATLAB to use 'opengl hardware' may resolve the issue.
Hope this helps!

Is it a new feature in 2020b? On the same machine, 2018b does not has this problem. Thank you very much for your anwser!
How can I check the incompatibility with graphic driver? I get the following messages with the corresponding commands:
>> surf(peaks)
>> ax = gca;
>> info = rendererinfo(ax)
info =
struct with fields:
GraphicsRenderer: 'OpenGL Hardware'
Vendor: 'NVIDIA Corporation'
Version: '4.6.0 NVIDIA 443.32'
RendererDevice: 'Quadro M2200/PCIe/SSE2'
Details: [1×1 struct]
>> info.Details
ans =
struct with fields:
RendererDriverVersion: ''
RendererDriverReleaseDate: '2020-6-5'
HardwareSupportLevel: 'Full'
SupportsDepthPeelTransparency: 1
SupportsAlignVertexCenters: 1
SupportsGraphicsSmoothing: 1
MaxTextureSize: 16384
MaxFrameBufferSize: 16384
