Quake 3 Arena should work without problems normally, it’s one of the usual OpenGL test cases here and thus checked regularly. Unlike Direct 3D hooking OpenGL hooking isn’t even timing sensitive, so there is not much that can go wrong besides an external factor, most likely an injection conflict with some other program on your PC.
BTW: After you got it to hook, please disable FluidSync in the vorpX options. Due to the way vorpX handles OpenGL, FluidSync doesn’t work well with it. That will be be done in a different way in the next vorpX version, for now FluidSync should be disabled manually for OpenGL games.
