Hi Fifi,
in WLHF (only in this big and beautiful harbour), try
Optimized WAC5.2 WideScreensGUI 1920x1080 Ahnenerbe :
https://www.dropbox.com/s/xohesnpn47...enerbe.7z?dl=0
this is a without full map version.
1900x1080 widegui + full map eats a lot of RAM and can cause CTD or other problems.
in all other harbours, no problem with ARB widegui 1900x1080
