Hi
My specs on launch day: I7 8700K 4.8Ghz, RTX 2080, M.2 SSD and 16gb ram.
Launching into JFK Airport New York would take an eternity and i was getting a few frames launching into the airport which is unplayable and constant freezing and stuttering.
My ram usage was around 15.5gb at ultra 1440p. I upgraded yesterday to 32gb ram and it fixed all my loading and stuttering issues. My fps before might have been around 20fps average with constant stuttering but now I get 35-45fps in new york with 1 or 2 stutters every 20 minutes which is a huge improvement.
My ram usage now goes between 17gb-27gb depending on the city. So I can say 32gb at ultra settings is a must.
