Any anecdotal (or otherwise) reports of this running under Windows XP?

System requirements say Vista+ but I gather it's a Source Engine game, so I figure there's at least a chance that it runs fine.

I found this - "Apparently the game has rendering problems on Windows XP. Some XP users reported having flickering lights/screen issues which makes everything brighter." - http://pcgamingwiki.com/wiki/Consortium#Flickering_lights

Thank you, triock!
