I tested Road Girs v1 table (that one I found) and it use about 400mb ram with "loading texture in table" disable. I onle play for few minuttes and seen it not crash here, even there is a bug in the table since the camera wont move...
I think you should checkout FP Future forum, since other have issues like this (howover you need register your self to see more forums, like bug report). If FP crash directly, it might been a sound issue as well a graphics driver problem. Some might have succes by using a bit older driver.... Checkout the FP forum and register your self, since some forums is hidden if you do not do that.
