I'm doing all of this. My OS, system page and the game folder are all on SSD. I have 16G ram in system. Task monitor shows about 9G of ram in use, 6.5G available, cpu at 10% and gpu (1660 super 6G GDDR6) at 40% when playing the game. When zoning, the gpu and cpu drop down to ~5%, the drives show no activity. The network spikes for a tiny bit but not for the duration of the zone load, more like a 1 second spike in traffic.
I am loading by using tequila.exe v 1.0.0.20 and starting Homecoming 64 bit.
I can play modern games at ~80 fps / 4k so hardware works pretty good.
I do have some usb external drives plugged in, but they don't have anything to do with the game.
Things I might try soon - fiddling with bios stuff, changing resolution of game and/or desktop, network trace.
Thanks for all the suggestions.
