I notice you have 'send HDR metadata to the display' Off.  How are you playing an HDR title?  It should look faded with it off like that instead of bright with lots of color.  Are you testing high quality 1:1 files with at least 109 mbps bit rate as well as low end titles like 720's that start making high demand on the GPU?  What about 4k 60Hz playback?  How about frame packed 3D?  If you can play assortment of well rounded title selections, this sounds promising. 

I check the 1st item in trade quality for performance tab for subs and the 2nd DXVA when doing native to let the GPU do the work instead of CPU resources via madVR.  Also, don't you want to put the subs below the video instead of in the video?  Preference.  You get better control/performance using separate profiles instead of using the same scaling algo's for all media, 460p, 720p, 1080p and 2160p if you find you run into titles that fail and need to start lowering settings.  Same with Processing fwiw.  Lastly, what does the detect hard coded black bars do for you?

yup what he said..

if you dont include the hdr metadata switch then you wont turn on the hdr.

i could be wrong but if you dont add the required frame rates in madvr field then you will only run at 60hz for all files instead of the required 23, 24, 50, 60.

''List all display modes madVR may switch to:
2160p60, 2160p24, 2160p23, 1080p24, 1080p23, so on and so on.

the above insures that madvr will switch to the correct frame rates for the file being played, if you dont you will just play at the default rate of 60hz. make sure that you tv, monitor or projector can play the rates. i have to stick to 60hz on my monitor as thats the only rate it does but my tv does them all.

while playing a movie press ctrl+j on your keyboard and it will pop a side panel up to show you the information of the file being played.
