BEST Setup

[it_dept]

Hi everyone,

Just finished a deadline using Vantage with crazy long loading times and multiple crashes.
The file was big, around 1,8-2gb, vrscene not live link.
The GPU memory usage inside vantage was around 19gb.

Current setup is:

NVIDIA GeForce RTX 4090

Driver version: 32.0.15.7283
Driver date: 14/03/2025
DirectX version: 12 (FL 12.1)
Physical location: PCI bus 65, device 0, function 0

AMD Ryzen Threadripper PRO 5965WX 24-Cores

Base speed: 3.80 GHz
Sockets: 1
Cores: 24

What would be the best possible configuration to avoid all those issues and being able to load a file in less than 30 mins and avoid crashes?

Would 2x 4090 work better than 1x RTX 6000?

The file is pretty much optimized as much as possible, is just a big masterplan with load of forest pack/vegetation/people.

Thanks

Do I understand correctly that loading a 2gb vrscene file in Vantage takes 30 minutes, not counting the creation (export) time for this file? This sounds way too much. The only thing that comes to mind is if you have asset files on network drives - loading them could be arbitrarily slow.

How much system RAM do you have? Have you checked that you're not ending up using the swap file?

The crashes you're having are probably because you're running out of RAM / VRAM (it doesn't have to be 100% full to fail to allocate a big chunk of memory).

Using two cards won't fix the memory pressure because each card has to keep its own copy of the scene. There are several cards with similar names, in chronological order: "RTX 6000" (Turing), "RTX A6000" (Ampere), "RTX 6000 Ada" (Ada). The first one has as much memory as 4090 and is slower, so no point using that. The other two have 48GB so this could be useful for huge scenes that otherwise won't work. The Ampere should be slower than 4090 when the scene fits in 4090's memory. Only the Ada card has matching performance.

Did you try to clean out your temp folder under user/appdata/local? Whenever I run out of vram, crash or loading takes forever, it seems to resolve my issue.

What also helps is to load in smaller parts, instead of one huge file. I typically would load in the geometry as the base and then import planting/people/cars etc as separate vrscenes.
You may then also be able to find which vrscenes causes the long render times.
