Low FPS MSFS 2024

I have been micro-tuning my MSFS 2024 - on my I79700k/RTX2070Super/64GB/2TBNVME3500Mbps/4k/6-800Mbps line - over the last several days - about 2/3 settings ULTRA with clouds low/clear sky TLOD low - also trying 1440 (doesn’t change much) DLSS Quality (most recent version) DLDSR 2.5 and increasing page file size and adjusting Rolling Cache 16-32-64 - doing pretty good so far but have to use frame gen (DLSS>FSR) and before I guess cache fills up with repeated flying in area may have FPSs occ down to 12-15 but generally 20-30 or higher (sometimes even 30+ without frame gen) and also moving over Community folder scenery related things, like Bijan, tree removal, flightsim.to detailed sceneries, etc -
