How does one get the new multipass option to work?

With the new preset, I get:

InitializeEncoder failed: invalid param (8): Presets P1 to P7 are not 
supported with older 2 Pass RC Modes(CBR_HQ, VBR_HQ) and cbr lowdelay.

With the old ones:

InitializeEncoder failed: invalid param (8): Older 
presets(default-lossless_hp) are not supported with 
NV_ENC_RC_PARAMS::multiPass and/or NV_ENC_INITIALIZE_PARAMS::tuningInfo


Otherwise, the minimum driver version requirement appears to be swapped 
between Windows and Linux?
