Hi there,

I had the same trouble as some of you might get running this demo on Windows XP.

First of all, the demo was not working at all for me. I've downloaded throught steam (yes the demo is avaiable on steam) and then the game worked. But I got freeze after a couple minutes.

I was running drivers 158.22 from nvidia. So I've upgraded to beta 160.03. Now everything is working perfectly, no crashes, no glitches and I've been playing for an hour.

You can get the drivers from www.guru3d.com.

Hope it'll help you out.
