Random crashes and flashing red boxes all over [PC]

Found the other graphics card. It's an AMD Radeon HD 6850 Sapphire (1GB GDDR5, whatever that means). Is this better than the current?

@MRayDud That does appear to be significantly better, yes. 

If you are comfortable swapping cards, do so and try a clean driver install, then check the game again. 

Thanks. 

I just don't know how do I get it running cause I tried installing every single driver it asks  me to and still says graphics card= NVIDIA 'something' and when I try to open there is just this box that tells me I don't suppotrt directx11

Your current comment does not relate to either of the two responses you received recently.  We were writing about HARDWARE and now you are going on about software instead, and suddenly adding a totally unrelated GPU source.  It sounds to me that you need to go through this entire message thread and figure out where you are in the troubleshooting process. 

You may find you are unable to determine what you need to do to such an extent that self-help isn't practical.  The official customer support may be a better idea for you.

We will presume that you took your problem to Help Center, as suggested, and the Game Adviser there got this sorted out for you. 

I'm really sorry. I thought that I had the right thing, until my uncle told me the graphics card that was in the box was NVIDIA, and that the Radeon was in some old pc. The Radeon is running now, but those red boxes keep appearing. It may be due to some issue with AMD graphics, but I can live with it. I just have to thank you guys for the help.

@MRayDud While the card is a solid one, it seems that the 6900-series cards had support discontinued late last year, so I suspect that this could be part of the issue. New drivers stopped coming back then, which I suspect is a factor with the red boxes appearing.
