Daz is [seizing] my RAM.. Help!!

Sahip3D

My video card has 24GB of VRAM, but even so, when I try to render something, for some reason 100% of my RAM is loaded before the card starts working.

This didn't happen before the latest updates, even with heavy rendering, and now it happens even with light rendering.

Does anyone know how to fix it?

Please try top avoid using offensive terms, especially in thread titles.

Iray needs to preapre the scene for rendering - Iray doesn't need all the information about morphs and joints, it just wants the final shapes, but it does need the full level of Subdivision and full image resolution, among other things. As a result it is gernbally considered that you need between two and three times as much system memory as GPU memory to take full advantage of the card - with only 32 GB of system memory even a moderately demanding scene (requiring 10-15GB of GPU memory) is going to fill the system memory.

Regarding the use of a word that you considered ugly in the title, although it is not a swear word and does not offend any person, entity or institution, directly or indirectly, I apologize, I thought there were only adults here.

Regarding memory, I understand and appreciate the information, but even with 32 GB of RAM, before the latest software updates this did not happen. The 24 GB of VRAM was always enough.

Is there any way to revert to the previous condition?

Your best option is to get 64 GB ram or more if your motherboard allows it, ideally ram = 3x vram. If you want to revert to a previous version of daz studio then you ask the daz support to provide the old installer. You may also want to check the drivers as they can use more memory depending on the driver version, typically older drivers use less resources.

p.s. However, in general you also need the scene optimizer to fit large scenes, no matter the card you get. Or you can export to blender and use the simplify options there.

p.p.s. Another option is to render in the viewport which for some reason uses much less memory, but of course this way you're limited to the viewport size.

Unfortunately, computer parts are very expensive in my country, but it looks like I'll have to invest some more money anyway.

Thank you very much for your support Richard and Padone!

Instead of monitoring your resource use with WIndows, might I recommend using HWMonitor - https://www.cpuid.com/softwares/hwmonitor.html

It will give you far more detailed results

 Nothing agains HWmonitor, but imho, it's a bit of overkill, and not particularly useful for this situation.

In general, all a user needs to know is how much system and vram studio is using, which task manager is fairly capable.

The one advantage of Task manager, you can see how much System ram a particular program is using, which i find critical when working in studio.

One big problem i have with HWmonitor, and GPU-z, they either don't report anything for my secondary GPU, or the information is all bunggled up between the two gpus.
