Hi Sarah.
That image above is telling you that the game requires Pixel Shader 5.0, Vetex Shader 5.0 and 2048 megabytes of Dedicated video RAM to run. The last column on the right shows that your graphics card has all three of these things (2048MB of RAM = 2GB), so you should be able to play it.
My card is an older one, so I get around 20 - 30 frames per second on medium to high settings. I don't mind the lower frame rate as it's not a fast moving game. I do, however, have an issue with some animal textures looking really poor, but I've been informed by Frontier Dev that it's a known issue and they're looking into a fix.
