To find out what Shader Model version you, we'll need to find out what graphics card you have.
To do that, go to start>search bar> type "dxdiag" (without quotes)>hit enter
A window should appear, click on the display tab, this should list what your graphics card is. Whether you have an expensive dedicated graphics card, or just a cheaper integrated GPU, most should have shader model 3.0 or later. You can copy and paste the info to a post, or you can click on "Save all Information."
This saves it to a file, which you can post to this discussion if you like.
