That should be enough.

 

The new layer view requires OpenGL 4 because it needs geometry shaders. Your graphical card supports OpenGL 4.5 according to this spec sheet: https://www.geforce.com/hardware/notebook-gpus/geforce-gt-740m/specifications

So I think you just need to update your graphical drivers. Once you've done that, Cura should be able to detect that you have OpenGL 4 support and allow the fancier rendering of layer view. Also be sure to disable the "Force layer view compatibility mode" option in the preferences.

I think your laptop has both an integrated (Intel) and an dedicated (nVidia) GPU. If that is true, you should be able to configure your ("Optimus") driver to launch Cura with the dedicated GPU.

You might also need to force windows to use your dedicated GPU for Cura. You can do that in the Nvidia control panel (right click desktop -> Nvidia control panel):

Thank you, my problem was solved

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
