Growing Irate with this Game

[Gryphon_]

An even easier tool to monitor GPU Memory use is the 'GPU Observer' gadget for Win7. If it helps you set up your game so that it's only using video memory within your limit, then post the results and settings.

If the game needs over 1Gb of video memory to play on anything but low settings then that will be something the developer needs to look at, as the cheapest cards over 1Gb are about $250 in the US now, and probably a lot more elsewhere.
