Wing Commander Fowler,
My guess you have very old drivers. There used to be an option to put the nVidia Logo whenever in 3-D
In
Display Properties >>
Settings >>
Advanced >>
GeForce
In there you will find under either (I cannot remember which) Direct 3-D or OpenGL the option to display the logo. Just remove the checkmark.
Also I would recommend installing the latest
nVidia ForceWare Drivers
Take Care,
Richard
