No problem.
I really need to go back through this topic and compile a list of the posts which still have useful examples in them. madVR has changed so much that some of them may not be relevant any more.

I would actually suggest dropping down to a "lower level" of chroma scaling (preferably Lanczos 3 or Bicubic 75) that you can run with the AR filter, than using Jinc 3 with the AR filter disabled - in most cases, it's a better trade-off.
It's really very rare that you need anything more than Bicubic 75 AR.

This comparison was done against Jinc 8, but it
is not a recommendation for people to use Jinc 8 - Jinc 3 AR actually looks better than Jinc 8 99% of the time. If I recall correctly, I left Lanczos 3 out because it's almost indistinguishable from Bicubic 75.
I probably wouldn't recommend anyone increase Chroma above Bicubic 75 AR unless they are already using Jinc 3 AR Luma, have a display capable of showing 4:4:4 chroma, and have GPU power to spare.

Again, I don't recommend SoftCubic with the anti-ringing filter.
I think the anti-ringing filter has been improved since this comparison was made, but these images illustrate what happens when you use SoftCubic+AR:

Pay attention to the edges of the X in particular.
I don't recall there being problems using the AR filter with other algorithms.

Chroma Resolution Test Pattern
4:4:4 and 4:2:2 examples using this pattern
If your display processes chroma in 4:2:2, there's no need to use anything more than Bicubic 75 AR - even that may be more than you need.
