Interactive rendering and UHD Cache question

[cecofuli]

Hello guy,
I'm doing some test with it,  and I found a strange behavior of IR..

(1) Classic simple interior scene: 4 walls with glossy, one window and CoronaSky.
(2) PT+PT.
(3) Start regular render. Northing strange: HD Record and rate = 0
(4) Change to PT+UHD (Precision UHD = 20)
(5) Start regular render: Computing secondary GI pass it's very long (oblivious) and HD Records is 200.000
(6) Good. Now Start IR: HD record only 30.000 and, when I move the camera, the FB update in "only" 3 seconds!
(7) I expected very slow IR with Precision = 20! And why only 30.000 HD records? Maybe when we will run in IR, does Corona "cut" some UHD rays?
(8) If I change the Precision UHD = 1, obviously the FB refresh, when I move the camera (I'm in IR) is much faster (half a second)

What do you think?

Interactive rendering uses some slightly different settings than regular. GIvsAA is divided by 4 (AFAIK), and UHD precision (maybe some other settings?) are altered too to make it more responsive. So this is expected.

Thanks Maru I though the same, but I wanted some other opinion =)
