So for madVR users it should be the ultimate subtitle rendering solution. Of course rendering subtitles at a higher resolution does come with a cost (slightly higher CPU and GPU consumption), but it shouldn't be too much, I hope...

There's one limitation: The combination of XySubFilter + madVR only works properly if your GPU is able to perform alpha blending in more than 8bit. Some older GPUs (e.g. NVidia 9xxx series up to 2xx or maybe 3xx) can only perform alpha blending up to 10bit. For these GPUs you have to enable the madVR option "use 10bit image buffer instead of 16bit". Newer generation GPUs have no problem performing alpha blending at 16bit. Very very old GPUs might not even be able to do alpha blending at 10bit. If you have such a GPU you may have to stick with xy-VSFilter or the internal MPC-HC subtitle renderer.
The GeForce 8600GT has alpha blending?
This here is another question I have. When the XySubFilter is installed, looks like this:

When the xy-VSFilter looks like this:

It's supposed to be so even with the XySubFilter installed? Another thing I noticed was regarding the pin info generated by lav. When the xy-VSFilter is installed, the pin info output equals pin info input, in the case of the video image is 720p. Already in XySubFilter, Pin out information generated is 2048x720. Is that correct?
