Fluid 4k60p vs Zoom Control
As far as I can see, at least on my set-up (see sig below), there is no way to get 4K60p and Zoom Control.
If I want Zoom Control, I can't use D3D11 in LAV. If I want 4K60p (@ RGB 8bits 4:4:4), I have to use D3D11 in LAV, or I get tons of dropped frames. The rendering time is fine, it's far below 16.68ms, it's the queues that are all near empty. Of course I only have that issue in 4K60p, I can play almost everything else (including 4K23p @ RGB 12bits 4:4:4) without any h/w acceleration. So unless I'm getting something wrong, it looks like I'll have to use manual zoom control until zoom control is supported with D3D11. Sharing this in case others are wondering why they are getting loads of frame drops at 4K60p.

I'm mostly preoccupied with DX11 not allowing hardware interlace, to be honest. Because that pretty much stops me from having a fire&forget setup when I'll move to a 4K display. |

Sure I could forget 4K60p more easily than zoom control, but I don't like the idea of having to fumble with settings when playing some files, so as I can use the lens shift memories on my projector to do the zoom control manually, I end up doing that for now. With 4 memories it covers 90% of the needs. Not as good as MadVR's zoom control, but good enough. I have to do that with my other sources anyway, so not a big deal.

With D3D11 native I have NGU upscaling on high without any problem.

But that's just with 4k60p right? Almost all content is of course 24p (bar one film that I can think of) and that isn't likely to change any time soon, so I don't think it'd be much of a problem. Either way, super-xbr seems to be a perfectly decent chroma scaler.

Anyway, as I said it's not a big deal, I'll just use manual zoom control until D3D11 native works with zoom control.

meanwhile, to bridge the gap in time : the side-by-side trick... does it send 2 Full-HD Pictures to the TV, so that in principle the PQ remains the same? Or is there a downscaling involved to 2 half-resolution pictures ? |

Don't overwrite your settings.bin in madVR's program folder.
