OK now there are 3 different versions of CoD. Is it V CoD (CoD 1) CoD:UO or CoD 2?
If it's CoD 2 you won't be able to play with your graphics.

5. We will get to that if nothing else works. At its most basic level, OpenGL is a specification, meaning it is simply a document that describes a set of functions and the precise behaviors that they must perform. From this specification, hardware vendors create implementations — libraries of functions created to match the functions stated in the OpenGL specification, making use of hardware acceleration where possible. Hardware vendors have to meet specific tests to be able to qualify their implementation as an OpenGL implementation.
OpenGL serves two main purposes:
To hide the complexities of interfacing with different 3D accelerators, by presenting the programmer with a single, uniform API.
To hide the differing capabilities of hardware platforms, by requiring that all implementations support the full OpenGL feature set (using software emulation if necessary).

he main reason I have seen this happening is not updated graphics but you have done that so it maybe a malfunction in the game you have. Just try the steps I said before and post back for me.
