Test Setup
Please read our testing methodologies and benchmarks and review format for an explanation on our procedures.

Game Setup
In all games we run in either DX12 or Vulkan API if possible. In Red Dead Redemption 2, Metro Exodus, Gears 5 and The Division 2 we use the built-in benchmark runs. In Call of Duty Modern Warfare, we perform a manual run-through at the beginning of the campaign run. In Need for Speed Heat we perform a manual run-through in the open world of the game driving through the city and up into the mountains.
Unlikely, unless you were constrained purely by VRAM and it was having to cache out of local VRAM often, which doesn’t seem to be the case in our testing.
However, we will re-run benchmarks and test directly PCIe 3.0 versus 4.0 in the future. We have many good articles planned, and that is one of them.
No driver issues reported on my end
