This is probably something akin to the "Maximum pre-rendered frames" setting in the nvidia control panel.. which used to have 0 frames as an option but hasn't had options lower than 1 pre-rendered frame since I think kepler launch? I remember I used to have it set to 0 with my GTX480 when that was an option. This also makes sense since nvidia gpu's don't have a hardware scheduler since Fermi so the driver has to have some buffer to work out what it's doing on the cpu.
If this is related to AMD gpu's still using a hardware scheduler then nvidia can't do much about it with any of their currently supported gpus unfortunately.
