Hi Lukas,
I am not with Laminar Research; just a flight simmer from downunder.
I am of the opinion you have not supplied sufficient information to provide an adequate response.
In the meantime you may get some relevant information from the following links found at https://www.youtube.com/watch?v=YysP4PAc5tc and also at https://developer.x-plane.com/2013/12/hdr-isnt-just-hdr-what-does-that-hdr-check-box-do/
It is also advisable to attach your log.txt file as this file can provide information on what is happening in your system.
Hope this helps
Glenn
