Disconnection on some maps.

I am not the only one having this problem, it's for every Intel user that has a Intel HD Graphics card.
So basically:

I can only go in maps such as, Hijacked, Nuketown and Cargo.
If I want to go on other maps, I get a message saying ''You have been disconnected ... blahblah''

Does anyone have a solution for me? I'd appreciate that, and would be so happy and can finally play on other maps.

Yes, upgrade your Graphics Card. Your Graphics Card will eventually not be sufficient. So why don't you upgrade ? Even a 50-100€ GPU will immedeately get you better games boh1

I'm sorry, I forgot to mention that I have updated my graphics card software for over 2 times and still no difference.
And yeah true about the GPU, I am getting a new one after school all I want is just survive with this one and have fun till that time comes.
