with DXVA native even measure peak brightness is disabled which is a couple of MS if it it used.
because i can't look into your system you have to make sure all use the same settings and no setting is used that the other mode can't do.

I wasn't trying to do a fair comparison, only to show what results I get with my current settings if I simply change the mode.
I didn't use a 16/9 movie because I thought black bars detection wouldn't be active, I used it because it has more pixels to handle than a 2.40 title, hence worst case scenario re render times (as I said).
I'm only posting results for the settings I was currently using. I'll adapt settings depending on whether I decide to use native or copyback.
Measure peak brightness isn't disabled when running DXVA2 native, not sure where that comes from.
You are correct though that if I was to disable the CPU features used in CB that cannot be used in native, the render times would go down in CB. I guess I'll have to test that.
