Coming from our Linux Community, we have cooked and packaged (in Windows) various Unreal Engine 4 samples for you to try on your Linux computers.
The following samples will only run on the x86_64 installations, as that is the only architecture Unreal Engine 4 currently supports on Linux.
Also, you must have an OpenGL 3.2+ capable graphics card to run Unreal Engine 4.
You can also access the console by pressing the ~ key and get some performance details among other things, by using the "stat" command, ie. "stat fps", or "stat unit" ...
Lasty, enjoy, because UE4 rocks!
