Don't I need to set a maximum --ref for DXVA, depending on the resolution, like in x264? --ref 3

Don't I need to set a maximum --bframes for DXVA-compatibility?

Or does the setting: --profile main10
restrict max --ref and max --bframes automatically?

EDIT: "x265 should set the level value on its own"-nevcairiel. Thanks.
Level 4.1 was a first-generation H.264 limitation, all of the later hardware could do 5.1 just fine. Likewise, main (not main10) @ 4.0 was a first-generation HEVC limitation, but now most can do main10 @ 5.0 without a problem. You can look up your decoder's actual limitations, since it's based on the hardware, not on DXVA itself.
