4k Cache - What's the latest? (2023/4 Update)

I'm also keen to hear what the status of this is. It came up again last week with our team wondering what we should all be using by default, but I had no straight answer for them.

The overall guidance there is to simply leave it all at the default. Being still experimental, we haven't revisited this to decide if those should even be shown, which is why there are no details any place on what they do for now.

(EDIT, of course the settings you normally adjust for the HD Cache like Still and Animation are still fine to adjust; just the two new parameters are best left as they are).

Not sure where development is on this, but came across a situation this week where bright light coming in through thin curtains was causing very strong blotches of light, around 30cm in radius, using 4KCache. Switching to UHDCache fixed it immediately. Whacking up the quality/lowering granularity for the 4KCache helped but never removed the issue.
