I’m using Virtualbox with 3d Accell is enabled to run a Win10Pro on top of my linux host.
Using the proprietary Nvidia driver (v390) for my GTX980Ti, GA are installed, dxdiag looks fine (see https://nonchip.de/paste/211).
I installed the launcher and ran it from the install dialog, even installed (but didn’t run) Fortnite.
But after a reboot now the launcher doesn’t even want to start and tells me to check if my gpu matches the requirements.
EDIT: the dxdiag linked above is from AFTER the reboot (=reflects the “broken” state), don’t have one from before to compare sadly.
