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.
I think it's always a good practice to set the Profile and Level you want. x265 does a good job of picking appropriate defaults for your content's fps, resolution, bitrate, etcetera. But if the values matter, and you set them, it'll let you know if you did something to violate those. And there's rarely any reason to not use the lowest profile compatible with your height*width*fps for entertainment content. Stuff enabled by High Tier makes sense for content acquisition (especially IDR-only).
