Background rendering.

[Background rendering.] Title says it all. Not everyone has 2 PCs to play with and when some renders take hours upon hours that is time that a PC is locked down. Granted, I can still use the PC but that just slows the rendering down even more.

What's the question? If you use the PC, it slows the rendering down, since it has to do multiple things at the same time. That's just how computers work. If you are asked to do ten things, instead of just one, you will be slower at all of those ten things, too.
think they want to know how to reduce the prioriry and maybe limit cores
task manager processes right click
You could try chaging the render target to "direct to file" rather than rendering on screen. That used to take up alot less resources,
I wonder if he is asking about sending the render to a background process so he could start working on the next project. Something that used to be an issue in video editing/rendering. Currently in Adobe PP you can export the render to AME then create/load a new project or continue editing the current project while it renders. However resources are finite and while performance in the editor does take a hit you can still work while rendering depending on the hardware/setup.
Currently I haven’t seen a way to do this with Daz. Maybe tricking the system and launching Daz Studio twice would work but I don’t recommend it.
I work with 2 DS instances all the time, no problem whatsoever setting up next scene in the beta while the public build is rendering, infact it's possible even on my IMac2015/8GbRAM to render simultaneously in both instances, if you keep the scenes simple.
ETA: I should add that I use 3DL, Iray might not like it?
I do too; simply download the beta and install it together with a few other things it requires. I use the PostgresQL beta too; it might be a requirement. It's necessary to uninstall the non-beta PostgresQL but the beta works fine with the Daz 4.12 release.
It works fine with Iray. I render on the beta using a TitanXp card which has no monitor attached and I compose in 4.12 using the built in Intel HD graphics; the monitor is attached to the motherboard, an Asus ROG Maximus X running Windows. This is actually pretty close to using two PCs but without the desktop clutter and with no issues about sharing the Daz scene files etc. The rendering process has pretty much zero effect on the interactive performance; Windows task manager shows the beta using maybe two virtual CPU cores of the 12 total along with 100% of the GPU.
I have seen problems from time to time. Recently I loaded a scene into 4.12 that was being rendered in the beta and it had lost a whole lot of surface settings. It looked like I had loaded a partially written or damaged file. This has only happened once. Problems can arise with Iray preview or dForce; both of these use the configured (render settings) graphics card and can cause an out-of-memory if a render is started in the beta. That's just resource limitation.
I've also changed the render settings not to use the motherboard GPU as a fall-back; if the TitanXp runs out of memory I just get an immediate black render rather than an incredibly slow one. That's something that is worth doing anyway in a dual assymetric GPU configuration.
In principle I don't see any problem using two PCs if some way can be found to allow Daz to run on a headless system. ManFriday's Render Queue can drive Daz via scripting however the Daz window still appears. If there is some way of running without a window presumably batch rendering on a PC with just a graphics card (no monitor) could be made to work. Daz also supports render servers, but I don't know how difficult those are to implement or whether they could be made to work locally.
If you are rendering on iray, in cpu mode, and giving it all your cpu to use, it will be slow as hell. If I am rendering with my 2080 super, I can usually do other stuff, like play in blender or surf the internets. In cpu mode, forgeddabout it, unless I limit it and keep a core or two away from DS. Oh man, this thread is necro lol.
I render in Iray in CPU mode on my iMac and I must say it makes my fan spin loud and takes awhile for still images and animations. Not even close to having an Nvidia card I'm sure. Previewing in Iray takes a while too depending how much of the viewport takes up my screen. I'm rendering right now and able to surf the net and type this although my iMac is a bit loud right now. I do have a Core i7 with 24 gigs of ram doing the rendering but I'd still like to get a PC for my Daz work. I'm just not excited about all the trouble shooting that comes along with Windows and graphics cards and Daz, etc. unless I'm ill informed, is it trouble running Daz with Windows? I'm planning on PC with a RTX 2070 Super. Hope they play nice.
Sounds like you are rendering with the CPU ... maybe this helps:
