Iray server GPU Vram half usage

yattagor

Good morning everyone,
I've been using daz studio for a few years but I really can't understand the use of VRAM by Iray server.
For example, when I try to render a scene created on a PC and loaded via bridge onto another PC with a 4090 RTX, Iray server, while saying via log that 24 GB of video RAM is available, only uses half of it.

You understand well that this is a problem because despite having such a high-performance card to lighten the work you are forced to go through an optimization process via plugins and manually which is totally useless.

Maybe other people like me have encountered this problem or it's simply me who, despite having made thousands of renderings and having read various documentation, am doing something wrong.

Regarding the video card processor, however, it is used entirely. This is exactly why I don't understand!
The workstation continues to tell me that 24GB is available but if I exceed 12GB the iray server iterations do not increase so it is not possible to proceed with rendering the scene.

I hope someone knows the answer to this problem and obviously I hope it is useful to the whole community.

I thank you in advance.

The amount of memory used will relfect the complexity of the scene - there is no speed benefit in using more, the bottleneck (as long as the scene fits) is the speed of the processing cores.

How do you measure the 12GB limit?
