Question

When starting RSTAB or RFEM, I get a message saying that the graphics chip does not support the OpenGL hardware acceleration. Unfortunately, the rendering in the programs is no longer as detailed, and the work is not quite as 'continuous'. Can I still use hardware acceleration?

Answer

OpenGL technology is used for 3D rendering, which must be supported suitably by the operating system and the graphics card. Since not every graphics card manufacturer is at the same level of OpenGL technology, Microsoft's technology serves as a reference. We use the standard Windows OpenGL features.

In RSTAB and RFEM, you can activate or deactivate the hardware acceleration (OpenGL) using the menu 'Options' → 'Program Options' in the 'Graphics' dialog tab (see Figure 02). In the same dialog, an improved smoothing (antialiasing) can be set to prevent the edge effect. These options are activated after restarting the program.

The mentioned options are very dependent on the used graphics card. For the work with RSTAB and RFEM, we recommend a graphics card that accelerates OpenGL functions in terms of hardware. This is the case with all current graphics cards. It is very important that the drivers of the graphics cards are always kept up to date.

We do not recommend graphics solutions that are integrated into the chipset or main processor (Intel HD xxxx, G xx, Q xx). Notebooks are often equipped with two graphics chips, a power-saving integrated into the processor Intel HD chip, and an additional more powerful graphics chip (for example, from NVIDIA or AMD). In this case, it should be ensured that RSTAB and RFEM use the powerful graphics chip. In the links below this FAQ, you will find further information on how this works in detail.
