Almost certainly not.i meant its not ram issue maybe GPU VRAM
Radeon RX580 w/8 gigs VRAM here. Watching hardware monitors, CP2077 holds quite steady using almost all of it. However, the system RAM usage keeps climbing and climbing and climbing. Temps are also staying fairly stable both on the gfx card and the CPU.
On several occasions I've actually had Windows complain about running out of memory, which is ridiculous. That's all about system RAM. And when I say, "Shut up, it's fine," the game generally has a CTD not long after.
