You need to look at "Both" his systems specifications. Also your reproduction on your hardware isn't relevant to his reported issue on his hardware, there are other causes of ReBar introducing oddness that are specific to systems themselves (Riser errors, a ****** up pcie controller, user modification of what core processes the interrupt of a particular driver) and that users with the same components also running the game (and youtubing it) without the stated issue indicates other aspects than just the driver are at play. As they always do but people want nvidia to fix issues with a crystal ball..... look how that turned out for microsoft and its telemetry based QA. a good majority of the those reporting fps drops across all games in the driver on the geforce forums simply had to restart the pc..... Heres that video again, of the 5950x that isn't stuttering and dropping fps across any games, which is in contrast to moab600's experience where the same cpu and a 3090 does drop fps in some of them. Rather than being disabled, the default behavior for unwhitelisted games is that transfers are limited to 256MB.
