Questions about UHD cashe

[denisgo22]

I have some questions about UHD:
For still image----------------
How well do the default settings /1/ for most scenes and cases?
What i need to do to get more /success rate/ in UHD, if it critical for render quality?
What number are successful or bad in /success rate/depending on the HD records--- 15/20/2000???

If I need to change default /1/ in UHD mode for rendering animations, or this work for most cases?

I'm not sure about that, but for performance increase i'm just trying disabling bump and reflections on the gi pass using rayswitcher.  Any loss if bounce energy can be replaced by increasing the diffuse slot albedo resultin in practicall ly the same gi result but without the noise. 

I hear unchecking low thread priority in the system tab dramatically speeds things up too.

You heard it wrong then. Unchecking low thread priority doesn't speed up rendering at all.

too late, this is our new "MSI 400" :).

BTW: I am expecting to find out that people who observed improvement were doing some photoshopping/gaming/... with max in background...

I just wanted to understand how works UHD, and in which direction to turn the settings, for different cases and scenes/
Can somebody explain it clearly???

I think that UHD settings sould only be tweaked for animation if you notice fickering on the output.

Actualy i havent opend and changed HD\UHD esttings since A7.

About the LTP, it should only be uncheked if you having memory isues and have a proper size pagefile on your harddrive. (For example super heavy exterior scene, something like 40M alive polys + 30 000M Scatterd polys)

Do you have any problems with it?
It should usually be left at defaults for stills.
If you are getting low success rate, this doesn't necessarily mean something is wrong. It can be normal for some scenes. There is no "correct" value for this.
