Many computers, especially laptops, have more than one graphics card available. Such systems often default applications to use the less powerful graphics card to save power. To ensure the best possible performance, make sure that Tekla Structures always uses the most powerful graphics card on your computer.

If you have a capable graphics card, but DirectX rendering seems to be slower than OpenGL rendering, your computer is most likely not using the correct graphics card for Tekla Structures.

To check which graphics card is being used, see How to check the graphics card used for Tekla Structures.

Note that running applications on a high-performance graphics card can significantly reduce the time a laptop can run on battery power.

These instructions are valid for Windows 10 version 1709 or newer. If you have an older version of Windows or if you want more configuration options, use the settings software provided by the graphics card manufacturer. We provide instructions for Nvida cards in this support arcticle.

  1. Click the Windows start button, start typing Graphics settings and click to open the app when it is listed.
