Project Cars FAQ page has shared several details on the game, including recommended specs.
First off, the game boasts 12K support. Of course, Slightly Mad Studios is slightly joking here, as what they really mean is 3 4K screens. If you make so much money that you can set up something like that, it should hearten you to know that you can do exactly this.
The SteamOS version joins the Wii U version in being indefinitely delayed, but the PS4/Xbox One versions will be out as soon as next month, so we know it’s not a case of protracted development anymore. It’s likely Slightly Mad will wait to release this around the holidays for PC.
