Textures renders noisy in VR Occulus Quest 2

Hello every one,

I uploaded my model from a blend file.
All goes fine in a browser viewer. But
when I look at my models through VR mode with the oculus 2, They do not display well the textures.
Textures are noisy.
I tried to edit my 3d settings through the meta oculus browser but it didn’t let me. A fail in the “bolean” appear. So I couldn’t make any change from the VR browser.

But back to my computer web browser everything is fine.

I do not understand,

thanks for your answers if it inspires you
best regards.
