Graphics issue: Popup textures, terrain line etc

Ive just gotten my new pc with a 4070ti gpu. Game is runnin smooth but Im experiencing issues with the graphics when loadin in battles, most noticeable in ground battles.
When driving around I see textures popup, on ground, buildings and foliage. The terrain also keep changing where i also see lines like it is updating the looks of the terrain 2-3 meters ahead of my vehicle.
Same result when lowering some settings to keep stable fps above 144.
Is it just the game? or is it because of my pc? Dont know if the memory bus of 192-bit is makin this issue? Ive tried to reinstall the game, updated and reinstalled drivers and nothin helps.
Am I the only one experincing this? and is there a solution to this?

Thanks in advance!
