You basically need it to properly display the graphics. It’s related to what graphics card you have.
These are the system requirements, by the way:
OS: Windows XP, Windows Vista, Windows 7, Windows 8
Processor: 1.2 Ghz
Memory: 1024 MB RAM
Graphics: OpenGL 3.0 compatible video card
Hard Drive: 500 MB available space
If you have that, but still can’t play it, then there’s probably a bug of some sort in the demo.
No big deal if you can’t run it yet though. The game will still be in Early Access for about a year, so by then you’ll probably have found a dirt cheap lappie to run it on. ;)
