I'm just going to copy this from Reddit since I posted it recently.
I have the following system hardware, and
these video settings at 1440p, and the game runs just fine. Averaging 110-160FPS in most places. In a city situation similar to
this video it might drop into the 45-70FPS range for a bit, but it is perfectly playable.
CPU : AMD R9 3900X
RAM : 32B DDR4 at 3200Mhz
GPU : MSI Radeon RX 6800 XT Gaming Z Trio

OS drive : 500GB Evo 860 SATA SSD
Game drive : A pair of 2TB Sabrent Rocket Q4's in RAID-0

Game client and save folders are excluded from security software.
OS is Windows 11 with current updates, and all supplier bloatware has been removed.
I have also covered previously how much of a difference simple changes like
CPU clock speed and RAM speeds can make, and also how much of a difference just some
bloatware can have.
