time saving render redraw interval experiment

StratDragon

I wanted to see what would happen if I rendered an image in Iray (using default settings) and changed the default 5 second screen update to occur after the expected render time elapsed.
Using the following scene assets

Genesis 8
YMK Margot (Renderosity)

dForce Pleated Ardor Dress for Genesis

SP Hair 008 for Genesis 3 and 8 Female(s)

Personal note, I found these on Pintrest but I don't use pintrest, and I'm the one who modeled these so kinda baffled here how they wound up on Pintrest.

The sandals and the bag are a WIP I'm messing with, I will post them on freebies when I've ironed them out.

using A single portrait HDR which may or may not have come with DS out of the box, and an 1660Ti 6GB I rendered my composition at 1072x1911 to a new window with a 5 second interval to update the progressing image the time to render until completion was 00:04:58

With a redraw interval of 300 seconds (5 minutes) the time to render until completion was 00:04:55
Huzzah!

So despite what my mileage was; has anyone seen significant time savings with this setting? My hope is others will try it, find out and post those findings here.

Hello StratDragon,

The redraw setting you're referring to, is it under Render Settings or Drawing Settings?  You mentioned "until completion" so I am assuming you meant Render Settings.  If that is the case, the "Redraw" interval is only how often the output is updated to the screen.  No matter how long you set this, the same amount of iterations will occur, but the output will only be updated when this timer expires.  Typically, I use 30 seconds because at 5 seconds, it updates so frequently that it impacts other software I may be using while the render is happening (but I render large images).  As always, YMMV.  A more frequent update also adds miniscule pauses to the render so that's probably why you see the slight difference in times.

Hope that helps!

Hi Dijitul,

Yes,this is an informal benchmark test. I generally render at about 3800x

I wanted to see of others did and what info they may have gathered
