I was just looking around and I noticed that on Steam (and everywhere else I looked) that the minimum system requirements are shown as 512mb VRAM, on the main store is says recommended as 512mg VRAM. I run the game at 256mg VRAM, the game is't all that pretty but it works. I just wanted to let you guys know because with my Steam experience, Steam to ensure bad reviews based on hardware don't happen as often, won't let you play some things even if your computer would run it without Steam. -Just thought you'd like to know
