For anyone having trouble starting Dying Light 2 on Linux. The particular error that I got was "./DyingLightGame: /usr/lib64/libcurl-gnutls.so.4: no version information available (required by libengine.so)"

I'm using Linux Gentoo as my distribution so hopefully this will help other people that experienced the same or similar issue to what I was. The fix is relatively simple but I couldn't find anything online to suggest it...

Open up the properties to Dying Light.

Select compatibility and tick the box for "Force the specific us of a Steam Play compatibility tool".

If it's not set by default then select "Steam Linux Runtime". This will then load up but can take a while for the first time but then loads up fairly quick after that... (this was from an SSD).

Enjoy! Hopefully this helped fix your problem and for future endeavours.

In the very unlikely situation that another Gentoo user is reading this...

I have the Steam package and Steam Meta package installed. Not that I think it will make a difference but I also installed all the dependencies manually.
