Crashes, Spazzing out texture

I was living with it at first but this is dumb you have not commented on the current problem with the AMD graphics card having these issues, me and my friend both have the same graphics card the HD Radon 7970, I had just made my house with 2 metal doors, and we came back on today and we got raided, That’s fair theses guys had C4 but only P250 and no amour, I had full Kev and a m4 with holo and red laser, I went out killed to popped a med kit at 70 health then crash not to mention the terrible frame rate and the Textures glitching all over my screen. if you add the feature of sleepers then fix the crashes, because its game breaking. Please do something!
