I don’t know anything about the rendering process or what makes a game use bandwidth of the hardware interface. It came to my attention that not all CPUs support PCIe x16 with all configuration and mostly, you need to have 1 NVME or two SSD’s plugged to the MOBO, that being equal to x4 lanes from the CPU. So you would need a CPU with a minimum of 20 lanes if you want to run fast NVME.
In this topic, I saw that Ryzen 5 1600x has 24 lanes so Maybe it’s good for having more things plugged to have a cheaper system but maybe not if you just buy one 2TB NVMe.
So I would like to know if upgrading my NVME and buying a GPU that can run x16 on PCIe 3.0 is a good idea for upcoming games like PoE 2 that will have much more detailed 3D assets.
