Just looking forward to see if madshi has time to integrate your implementation into madVR!

About the resolution enhancement (i.e. sharpness) of your image samples, my eyes feel :

Nearest >> NNEDI3_32 > NEDI > Jinc3 (+AR or not?)

Of course it definitely causes serious jaggy / unstable edges on motion objects with Nearest scaling mode.

In fact sometimes I still notice that with Luma NNEDI3_32 mode. Luma NNEDI3_64 mode solves that to give more stable motion like Jinc3AR and even more sharper image, but the cost is somewhat too high for HD contents. It will be great if NEDI allows to preserve better original resolution + same motion edge stability than Jinc3AR while it maintains the similar cost.

ps: My TV is Sony 65" HX920 with reality creation option (i.e. super-resolution function) at 20%. But it is still able to tell some difference among different scaling options in madVR. There is no need to say, madVR's Lanczos4_AR, Jinc3_AR, NNEDI3 options have better performance than the ability of TV set's scaler.
