Probably obvious, but are your graphics card drivers reasonably new? If you're using whatever Windows automatically loaded, they might be weeks or months older than the newest AMD or Nvidia versions. I'm using 0.6.0.0 and have been for since it came out, it works fine with Elite in extended mode. No issues whatsovever. Running a gtx970, newest drivers, i5 3350P, win7pro x64. So strange that it doesn't seem to work for most people. I did have to uninstall, reinstall 0.6.0.0 once when I first downloaded it due to a hiccup of some sort, but at that point it wasn't even running the 'demo scene' right, a fresh install fixed that.
