Do I really need to run Texture Res on Medium with a 10GB RTX 3080?

Of course I use addons like planes and sceneries, of course vanilla sim with a C172 is a better situation, BUT at the end of the day MSFS should be the part of the equation that manages VRAM. And I´ve found a full VRAM is causing my immense stutters, Look at the fps in the above screenshot. Thats 27fps on approach into EDDF with the FENIX, Im absolutely NOT maxed out on settings, Im on single 1440p with 100 render resolution, no DLSS (because my fps do NOT increase with DLSS, i rather have the clarity).
