Rendering and sounds systems are broken

I’m grinding Sweden and its the worst experience I’m having since i started playing the game ,beside the under-preforming vehicles sometimes i don’t hear enemy vehicles neither sometimes they would be invisible aka not rendered ,in some cases their engine sounds renders when I’m looking directly at them or if I’m extremely close even for vehicles with loud engine sounds for example the Abrams ,which makes me too late to react ,there was that time i was killed by an m1 kvt and when the kill cam switched on him ,he wasn’t displaying any sounds and its not the only occasion this happened ,it happen too usual ,sometimes gun fire isn’t displayed ,and for the rendering system ,there was that time i was holding a alley ,i knew there would be a leopard 1a5 pushing ,he was invisible until he stopped Infront of me and rendered before he shot me by less than a second ,sometimes they do not even render ,there was that vk3002 that was invisible and not even rendering ,he wasn’t making any sounds neither any track prints and he was Infront of me shooting me ,even the kill cam showed that he is Infront of me ,that wasn’t the only time that happened ,i tried running diagnostic files and it didn’t work and checked my files and it showed nothing is wrong with them ,i don’t know if my files are scripted (broken) or its game issue because im starting to lose my mind

The Abrams has a quiet engine, it just rattles
