This is really more of a question than a compliant.
Right now, I'm pushing all 11 GB of a GTX 1080 Ti.
I'm considering upgrading to a system with 2 RTX 1080 Ti cards connected through SLI. Each card would have 11 GB.
Will iClone recognize the new config and give me 22 GB to play with?
Having all that memory would be handy for my current project.
Any guidance on this would be most appreciated.

You do not really need that much VRAM unless you are rendering. The last discussions I had here, showed that iclone does not recognize 2 video cards together like Blender does. But I am not sure about the SLI part.
Blender Cycles uses two GPUs for rendering 2 frames at same time, does reducing the rendering time. But because iClone uses realtime rendering, it has different rendering structure and with Blender 8 realtime rendering will be added too, so I doubt using two GPUS will help.
Not sure if any new updates that has changed with iClone.

At the moment iClone still does not offer support for SLI. It has been stated that this is being looked at, and should be available in some future version.

a) As Gerry said, iClone does not support mult-GPU setups. They have not even announced a tentative timeline of when it could happen, so don't buy into an SLI setup for iClone.
b) Adding a second GPU does not double your graphics RAM. Basically each card has a copy of the same data in memory, and they just render different pixels, but two 1080Ti cards will not equate to having 22GB of VRAM.

Thanks so VERY much. The challenge that I'm having is a crowd scene, which is maxing out my graphics memory.
Perhaps the reducible geometry feature in CC3 (not sure I'm naming it correctly) will help with this.
Of course, I can popVideo parts of the crowd and reduce 90% of the scenery to a flat plane, etc.
Would rather avoid this, though. Perhaps it would be best if I just asked if and where the configuration I'm considering would be overkill. I'm kinda an iClone fanatic and do all my work in the Reallusion environment. I don't see this changing. I have a decently high-end machine now, but I'm thinking of upgrading to the configuration below and am wondering where I might have overpowered or underpowered. Any suggestions welcome.  |

It is recommended to use gtx gpu rather than a quadro gpu. gtx 1070 or above is good for iclone.

In the meantime something you could do is export your crowd characters with a lower texture resolution, for people in the the far background you can lower all they way to 256x256 textures, and for closer ones go with a resolution of 512x512. This will help you lower your memory usage, and if you are not doing close ups you can probably use 1024x1024 for your main characters and be ok

I also was concerned about your choice of GPU.
Some high-end cards are actually not great for "gaming," and iClone uses a "gaming-style renderer." It has to do with the type of math involved.
For a high-end machine like that, I'd suggest the new RTX 2080Ti. I wish that beastly card had 16GB of memory (it "only" has 11GB at the time of launch), but it should be an awesome card for iClone. I don't know if 3rd party companies like EVGA will be able to make 16GB variants of the card or not. But I think you'll be better off with an RTX than a Quadro.
Of course, you could also get a GTX 1080Ti (also a fine card) for a reasonable price very soon, and wait 6 months to see what else happens in the RTX 20xx family.
(EDIT: I forgot you said you are already pushing a 1080Ti to its limits. So it is a fine card for most people, but obvious you are not "most people." )
I also question (not out of jealousy) the choice of a 2TB SSD. As long as you store your project files and stuff on the 2nd drive, even 1TB leaves a lot of room for software installations and temp files. Hey, I wouldn't turn it down, but I haven't even filled up my 500GB SSD yet. I have a 1TB SSD as a "future upgrade" idea, but when I set up my SSD I told windows that "My Documents" is on my F: drive, so that helps keep a lot of junk off the SSD.
It sure looks like you're in for a fun time. :)

AH! I've been exporting from CC in the default each time rather than creating a avatar. I never thought of creating them with different resolutions. That should work quite nicely. THANKS!!!

I decided to go with a RTX 2080 Ti, drop the system SSD to 512 and add a 2TB SSD data drive.
I was gonna use the HDD for backup but decided to use an external drive instead.
Thanks for everyone's help!

I suspect CC3 will also help greatly (and you HAVE pre-ordered, right? Because you will want the full version, which can indeed export the reduced poly avatar, or so they say).
I have never regretted getting the 2TB SSD (and I also have another 2TB SSD data drive). You can never be too rich, too thin, or have too much disk space.

Once CC3 is out you will have the option to use lower-poly versions of characters, which should help with crowd scenes.
As others have pointed out Quadro is not recommended.
EDIT: Kelley already mentioned CC3...:blush:

Hi,
for massive crowds you might want to check Anima XYZ SW.
It exports animated crowds in FBX format, which can later be imported into iClone.
It also include a feature to split the crowds into multiple FBX files which helps to bypass the limitation of 3DXChange, which is still based on 32b SW architecture,
Regards
Roberto
