Skip mantle question when launching game

Instead of clicking the blue "Play" button, right click "Beyond Earth" in the library list, then choose "Play game..."
For whatever reason, this option skips the Mantle question and directly launches the game.
Of course, we are talking about a PC game; your experience may vary.

Thanks to @Dirty Beach finding a way to do it from Steam, this gave me a process to hook into and watch running to see how Steam does it.

The short answer is running the CivilizationBE_DX11.exe with a -DX11 command line parameter. This allows you to start straight into the game without a pop up, and allows cloud saves to be enabled!

Of course, if you just make a shortcut straight to the exe and throw command line parameters on it, Steam asks if you are sure you want to use them. This just gives us a different pop-up. However, this question shows us how to deal with that.

TL:DR; Create a shortcut to your steam.exe. Modify the target to be:

C:\PATH\TO\STEAM\Steam.exe -applaunch 65980 -nosplash -DX11

Modify Path to steam as appropriate

Theoretically, you should be able to just launch the game through the game's executable directly (e.g. using a shortcut).

However, at least in my case this results in the following error message:

The Steam servers are too busy to handle your request for Sid Meier's Civilization: Beyond Earth. Error Code (41)

You can still give it a try though. If it doesn't work, just stop trying and start the game as usual:

• Go to your game's installation directory. This will typically be <steam library root>\SteamApps\Common\Sid Meier's Civilization Beyond Earth.
• Find the application CivilizationBE_DX11.exe and create a shortcut to it (e.g. by dragging it directly to your task bar).

As an alternative, right click the Steam icon on the task bar and click the game's link under Recent. This should launch the game directly.
