GeForce GTX 1050 Ti: Slightly faster than the 1050, with 4k max averaging 46fps and 4k min getting a steady 60fps. GeForce GTX 1050: 4k max is mostly playable, averaging 42fps in Blighttown, and 4k min nearly maintains 60fps with a 59fps average (and 49fps minimum). 4k min is mostly playable at 45fps, 1440p max hits a steady 60fps, even with a modest CPU (Core i3-8100, Ryzen 3 2200G).
Radeon RX 560 4GB: Struggles at 31fps 4k max. This is one of the more demanding areas in the game, and I specifically found a spot near the elevator/lift where performance was even lower than elsewhere. Here's the short list of cards I tested that couldn't maintain a consistent 60fps in Blighttown at 4k and maximum quality. You'll want a PC that can handle the remaster at 60fps, but what sort of hardware will that take? I'm not going to bother doing the full performance analysis this round, because it turns out the hardware requirements-even in Blighttown-are quite modest.
