Hello ,

i have posted a problem, that on windows 10 cgx windows is not working correctly.  
it’s not working with bConverged also with CalculiX Launcher.  
I have fixed with Calculix Launcher by setting app graphical performance to high performance.

A glad to know! I also had issues with the bConverged executable.

As an alternative:  
Currently I use the linux one via WSL layer. IT works very well, although for big models its quite slow due to the lack of accelerated graphics. Nonetheless has the advantage to use the native and must updated version.
