'Enhanced graphic pack' message?

When I start the game I get a message something like ‘enhanced graphic pack not loaded’.

Anyone else getting that?

Game seems to run ok.

I am the same as you, but I can’t find where to install it.

Enhanced Graphics DLC is now available on Steam. Apologies for the delay, but you should see it for free on the Steam store page.

Where do you find it ?

On the steam store page:

Looks like you can download it here too
