Mesh Triangle Count Explodes in VR?

Hi everybody,

I’m making VR app and I’m dealing with a problem regarding triangles count of object.

For example the original mesh has 700,000 tris.

But when I play in VR mode and I check with stat RHI to check performance, it appears to be 6 millions tris.

I don’t understand why, it’s the same mesh so it suppose to have the same tris count, but in VR mode it appear 10 times more tris count
