Daz doesn't use optix prime any more ..
I't's not checked in my advanced settings
and yet my log file is littered with these messages...

New scene or a saved scene from when the setting was available?
that line was from a text log for the rendering of gothic ruins... and I pinkie swear that optix prime is not turned on and hasn't been for several years if ever.
That checkbox should have gone by now! It's been at least a couple of releases since it was removed completely.
actually I did do that render in 414 but basically I (gasp) use the last 412 that is social because I often render one scene while working on something else and have actually had 3 or 4 open at times.
---
If I notice I need a piece from an older scene I'll open that one and save the piece out to merge with the new scene.
---
you can use the latest and greatest and still open the older ones at the same time.
render tonight 4:14 scene created yesterday and today.

there is no optix prime option in 4:14 ... (and not checked when I rendered it in 412 and still optix is being intialized.
---
now is thsi something that daz does with there implemation of iray ... or is it the iray engine doing it.
----
OH, I'm still having issues with the render talking off and using all system ram... not cpu .. system ram.. not gram on cards .. 64 gigs on mother board..
---
And for course as noted often.. Daz does not release video memory from render to render.
---
I'm sure it can be done.. my games would only run for 5 seconds or so if they didn't clean the video buffer to make room for new data.
when you say iray .. .do you mean the iray renderer after iit's been called by daz but why would it choose to call it and then say it's not supported?
Or is daz automatically deciding to call it?
but why is it intialized and then followed with the other messages.

so why would iray turn on something and then decide it wasn't used... or is daz calling it and iray saying screw this call?
---
if you can something in a subroutine and get an error message why would you leave it up and generate a set of error messages during the run?
It is, "Iray saying screw this call".
There was an overlap period.
There were (a couple??) of releases of Studio with the newer Iray but still having that checkbox sending optix_prime settings to the new Iray.
The log is set to "maximum verbosity" so we see even the most minor warnings.
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/change_log_4_12_1_118#4_12_1_8 I hadn't realised you were using an older version of DS.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>render tonight 4:14 scene created yesterday and today. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
4.14... same message.
that's not an older version... and even if it was I didn't have the box checked.
I started programming in 1978 ... it would have only taken one run through with the box checked to uncheck it.
---
The question is and was... does DAZ call the optix prime before the render is handed to the iray or is iray in a part that daz has no control over calling the optix.
---
And of course it's set to verbose... you can't spot a problem with minimal information.
---
theoretically if one opened the daz code or any dlls associated with rendering and did a search for optix prime it should not appear anywhere in the code?
In which case there's something in the iray code.
Daz Studio does not call OptixPrime - Iray does use Optix (version 7 currently).
Studio no longer has any way to call (or disable) Optix. If Iray detects it in the GPU then it is used.
(It's the same for the CPU, if you're using a CPU that supports Embree then Iray will initialise Embree, entirely automatically.)
As I understand it, the Iray renderer has always been a sealed black box, solely under nVidia's control.
