Textures arent loading after few matches

Since one month i have annoying problem after multiple rounds.
Most textures are in ultra low quality and i can see through walls because they are not loading. And if the match is finished I´m stuck in the loading screen and need to close WT in taskmanager.

The best part is i can see tanks behind the walls. But i cant see tanks far away they only appear when you look at them or they shoot
