I usually set bufsize and maxrate as the same. I cannot find anywhere that shows how high bufsize can be set to to maintain DXVA hardware decoding, so I use the following for all my encodes for x265.

480p:--vbv-bufsize 12000 --vbv-maxrate 12000
1080p:--vbv-bufsize 20000 --vbv-maxrate 20000
2160p:--vbv-bufsize 25000 --vbv-maxrate 25000

These have all resulted in DXVA compatible files.
