I reported this in another feedbacktracker but it didn't get addressed and was blamed on me, which I have my drivers up to date and it's still happening.
So how this occurs, the buildings will sometimes just glitch out to where it just shows the barebones frame of the windows and then full textures of objects inside the building.
This isn't just with me, this happens to a lot of people, and it's not just a problem here, this is a problem that sporadically appears in DayZ typically on the Apartment buildings where entire sides of the building just won't load or render in till you get close.
This has been going on since Day 1, and has never been addressed, this also slows the game down dramatically, so I think it's a memory leak that you guys have in the game, but we won't be able to know till you give us the full code.
