4.8 gb vram for this simple scene is a lot! Not to say way to much. Let me guess, you use g8?Well I have my animation (image series) rendering and am having some serious problems with the rendering speed in Daz 4.12. I have a fairly simple scene with HDRI lighting and am rendering at 4k. When rending the first image in the series it takes ~3 minutes, however with each successive frame it gets slower and slower. By about the 5 frame it's out to 30 mins. Updated my video card drivers and am currently downloading the latest 4.12 beta. If anyone as seen this before and has any ideas on how to fix, I would appreciate.
Scene Processing Details:
Resolution - 4k
Iterations - 40
Video Card Memory - 4.8 of 6.0 GB
System RAM - 10 of 32 GB
Running a GTX1060

EDIT: I think the problem may be video card memory related, hence have run scene optimiser to simplify some of the textures and remove some of the bump maps. The amount of video memory appears to be still however increasing very slightly with each successive frame until it reaches the point at which the textures can't be stored on the video card and then the rendering speed dramatically reduces.
If you have other assets in the background, remove them completely. The wall in the background is far enough away to remove all, but the base color maps, if there are any. The ground looks like it could be compressed further without loosing too much quality.
G8 has a lot of unnecessary textures you only really notice in closeups:
If there's a map in any of the "Glossy" channels, remove it, same for "Top Coat" and "Metalic Flakes".
The clothes can be compressed further, you won't see many details after denoize anyway.
You could try the camera mentioned in this thread. I've used something similar a few times. It obviously changes the light a little bit in some scenes because it uses iray section planes, but it's not really noticable and worth it most of the time.
If this still isn't enough, you could try the batch render that was mentioned here several times (the one that restarts Daz).
aaand if nothing helps, render the background without the girls one time and then the animation with the girls with only the blue.... thing on the ground (I don't know how it's called in english^^).
