I suppose this was a guess based on the rendering time numbers reported by madVR. What you could do is to actually test whether you can find a situation where there are actually dropped frames in real life with "use a separate device for presentation" turned off while there are no frame drops with it turned on.

No, certain videos do start dropping frames when I have that option disabled. Plays fine with it turned on.

Yes, all with 0.85.5

Now the question is whether the benefit of linear light downscaling is higher or the benefit of lower aliasing with Lanczos.

One of these days, I should try and find some good film-based samples, and do a proper comparison between all the downscaling options. (measure performance and evaluate image quality)
If you are using linear light scaling, there doesn't seem to be any other option worth using, other than Camull-Rom with the anti-ringing filter enabled though. Everything else seems to suffer from particularly nasty ringing.

What about the same for blu-rays?

If you are using madVR with LAV Filters, DVD playback should work in MPC-HC.
Blu-ray requires something like AnyDVD HD to remove the encryption first.

It seems pretty useful for some SD content (where you need higher scaling factors).
I am refering to this post from him.

To be clear, I have only found two or three samples
total where Jinc 8 actually looks good with Chroma. These are the same samples where I would also recommend SoftCubic 100.
In most cases I would recommend Jinc 3 AR for Chroma if your system can handle it. I haven't done as extensive testing with Jinc on Chroma as I have with the other algorithms (it hasn't been around as long) but there don't seem to be any real drawbacks from using it.
In fact, Jinc 3 looks better with that sample. A little softer perhaps, but much less ringing.
Notice the dark line in the right side of the A with Jinc 8. (ringing)

While it may be better for the resampling process, once you go above 96kHz, you tend to get worse results with DACs. Benchmark Media has a paper on this with regards to their highly regarded DAC1 that goes into the details of why this is.
