Now in my initial ARC B570 review we looked at the cards performance in a best case scenario system, a PCIe 4.0 machine with ReBar enabled. You've probably heard it 100 times but ReBar or Resizable Bar is essential to get the most out of Intel's Arc graphics cards.
Today we'll be looking at how the card performs in PCIe 3.0 mode, with ReBar enabled, and then turning ReBar off to see how bad performance becomes. Will our games really go from playable to unplayable on this modern entry level GPU?
