F1 2019 is not a very stable game, it tends to "crash" often.
To get a better experience I decided to test some different setups with my AMD RX560.

Default Leap 15.1 Gnome + AMDGPU drivers -> time trials work but career mode crashes.
Default Leap 15.2 Gnome + open source AMD drivers -> career mode works for a few minutes, before it crashes out.
Current tumbleweed + IceWM + open source AMD drivers -> everything works, no crashes after 5 hours of gameplay!

So it seems that the latest software and the lightest install mode really pays off.
I made a separate partition and use the same home partition but it works.

Just wanted to share for all the F1 & OpenSuSE fans!
