Here is the DxDiag Report. I am not sure I know what Vsync is to see if it enabled or disabled. I tried both 512 and 1024 texture size. When I tried 1024 texture size I made sure I downloaded the high graphics download on the web site.                                                                                                                                                                                                                                       ------------------
