The Vertex Culling Extension Problem

I’m trying to use this extension on my GeForce 3 Titanium 200 but it’s not having it. Is it not available for the GeForce? Has it been changed or upgraded to something else? Here is my code to check for the extension:

if(strstr(extension_list, “EXT_cull_vertex”) != NULL)
glCullParameterfv = (PFNGLCULLPARAMETERFVEXTPROC) wglGetProcAddress(“glCullParameterfv”);
UseCullVertex = TRUE;
MessageBox(NULL, “Cannot find the OpenGL Vertex Culling Extension!”, “ERROR”, MB_OK);
UseCullVertex = FALSE;
return FALSE;

No. Click here for a list of GPUs that do support the extension.

Ok, thanks.
