I'm waiting on my 16gb sticks to come in the mail, but I wanted to know if I could play the early parts of the game in a playable state(60fps) on just 8GB of ram?system specs: Ryzen 5 3600 cpu, AMD Rx580 8gbvram gpu, 8 gb ram, 240 gb ssd. Win 10.
Welcome to the forum mate. As above, just give it a try, you have nothing to loose. You can mess with the settings to see if it helps as well.
I have been playing the whole game ever since with only 8gb ram, early middle and late. There are occasional freezes, there are large pois that will drop you framerate but I can manage. Don't know if you are more picky with performance but I would say you CAN play, yes.
