Title says it all. See attachment for a screenshot of a UHD video downscaled on youtube.
Well, this remained unacknowledged...

By the way I have an Nvidia GPU, in case downscaling quality is dependent on driver/manufacturer.

I remember from testing with progDVB that with EVR only Intel did downscaling properly, on Nvidia and AMD based platforms downscaled images looked horribly aliased.

That is because I'm fairly busy. Does this happen by default on YouTube or only when you manually select a resolution higher than what YouTube is selecting for you?

The latter. But Youtube is not everything. Many resolutions might not always be available.
