What are the advantages for the speed of the graphical display if I activate the OpenGL hardware acceleration? How it looks like when using virtual machines?


RFEM uses OpenGL for the graphical display. If available, RFEM uses the hardware acceleration of the graphics card. If this does not support hardware acceleration, RFEM uses the software implementation of Windows OpenGL.

In the case no hardware acceleration can be used, the graphical display is considerably slower. The extent to which this has a negative effect on the usability of RFEM depends on the size of the processed RFEM models.

For many (not all) hypervisors, it is not possible to use the hardware-accelerated OpenGL. RFEM would basically run in the virtual machine. However, the graphic display would be slower.

We recommend to test on a typical RFEM model whether the speed of RFEM in the virtual machine is acceptable.

Please note that our Support can only help you to a limited extent when using virtual machines.
