From what I can see, XySubFilter should combine all advantages of the MPC-HC internal subtitle renderer (high-resolution rendering, DXVA decoding compatability) with all advantages of VSFilter (correct colors, correct drawing of all ASS effects) and all advantages of xy-VSFilter (less CPU consumption etc). 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.
