Well . My friend has the same problem . The only way to fix it is to get a card updates , or to get a better card . But what my friend does is , when ge goes in-game . he gets a shotgun and keeps shotting around , that "forces" the pc to load the textures . this also works with cars , get a car and press accel and brake/reverse at the same time . it will smoke the wheels and the textures will load . The only way i see here for you to fix this prob is to get a a betters card .. or keep following one of the instructions above ...
