Bad PC Texture loading/LOD

Hi,

I have an RTX 4090 but in EA WRC I get terrible texture pop in, a classic example is La Maris. When you reach the first right had turn with a small wall (a small bridge) the texture of the wall is just a grey blob, like something from PS1 era (or worse). If I slow down after about two seconds the full textures eventually load. At the same time often on the road surface there are squares of low rez textures.

Does anyone know any tweaks that can get the engine to actually load the full sized textures? I know this is to do with UE streaming, but it looks terrible and ruins the experience.
