Missing 3DTECHPREVIEW command in AutoCAD 2024

[lwc-light]

I can't find 3DTECHPREVIEW command in AutoCAD 2024. Is the command deprecated? What is the use of this command?

Hi,

In AutoCAD 2023, the 3DTECHPREVIEW system variable has been deprecated. Use FASTSHADEDMODE to turn the new 3D graphics engine on and off. A restart of AutoCAD is no longer required. >> Click <<
