GPU memory full?

Hi D5 Team.

I’ve encountered problem here.

Previously i’m using GTX 1060 4GB. Although the rendering for 1 image took about more than 1hr. But still can running it.

Now, i’ve upgrade the GPU to 3080ti with 12GB…the problem is…my memory almost full? :sweat_smile::sweat_smile::sweat_smile:

The model almost about the same. Just add on some trees.

I’m a lumion user previously, when this kind of thing happen… basically we just split the sketchup files.

For example : 1 Hi Rise development with 3 blocks apartment & carpark multi storey. We just split each block. So total 4 files. Then import on the lumion. The memory issue solved.

Its like merging as we have it in D5. Although i’m not trying the merging method, but i did try to do same as what I’ve done in lumion. But no luck.

I’ve done much bigger 3d model in Lumion, the method works fine although only with GTX 1060.

Any help will be much appreciated.

Thanks.

And i just try delete everything inside, scene, layer & object. But the GPU memory still high usage? :sweat_smile::sweat_smile::sweat_smile:

Now my image rendering become black image…this is 2k resolution.

only manage to render at 900x605… :dizzy_face:

Hello,
sorry to hear that you ran into the problem. Could you try opening the demo scene of D5 then check the result? Also, please run D5 benchmark tool then show us the result:
D5 Render

Besides, the Windows resources manager may be not accurate, you can try monitoring the VRAM with GPU-Z.

If the problem persists, and it happens to a specific file only, then we may need to check your file for further troubleshooting.

To confirm, your video driver is downloaded from Nvidia official?

Yes, driver from nvidia official.


Hi, how’s the rendering going recently? It can render normal images, right?
From the benchmark results and GPU-z, we think the GPU works as normal, but you may need to make sure the power supply is large enough.

Hi Oliver,

Sorry for the late reply. Finishing off my annual leave for two weeks. :laughing:

I’ve tried yesterday, it works fine. Rendering 16k image at 16min.

I dont think because off PSU. Coz already using as per Nvidia requirement.

Not sure if its clashing with anti virus software (coz i’ve just uninstalled Avira Anti Virus yesterday).

But will keep on update if there is any issue.

Thanks. Have a great New Year to all D5 teams. :blush: :hand_with_index_finger_and_thumb_crossed:

Hi, I also have somewhat similar issue. My GPU core is used at 40-45% but the VRam is used at max. Resulting in very time consuming renderings.

Having same issue. Anything to be done?

Hi @charles.collin.2

Can you provide us with the full context?

  • Does this occur only in this specific file? Or to all of your files?
  • If it’s file-specific, how heavy is it?

Please also send us the following:

@clov,

I’m quite new to D5, but testing its limits.

The orginal file indeed is quite heavy (13Go of assets), I try to make a file where I can preview all trees. When I start rendering, it fails at the end.


Just having the scene open, im at 90% memory usage…

Maybe there is a “proxy” way to do this I’m not aware…


EDIT
I tested with a more modest scene. I put only 70 low poly vegetation assets (all different).
4k rendering
here is my performances.
Still 50% of memory used … this is huge no ? for a basic scene

here are my pc specs

So if you can help me understand why the memory gets overloaded so quickly I will update my way to think in D5 modelisation.

thanks for quick support,
appreciate

Hi @charles.collin.2

I just want to clarify that generally, different CPUs have little effect on D5. However, it is recommended to turn off CPU overclocking for stable performance.

D5 is heavily reliant on the GPU of your device; hence, the load is mostly carried by your GPU. The CPU will just initiate the software, loads its assets (models, textures, etc.) from storage, and manage the overall application logic. You may want to check if there are other application that is opened that may have contributed to the spike of your CPU usage.

Ok , got it.

Just want to know, the GPU doesn’t seem that overloaded … (15% used here). But the memory is almost full. Is that the issue? We are talking about my PC memory right, not my graphic gard memory ?

And finally, is there anything I can do to lower that stress on Memory ? Empty cach or somthing ? Or just upgrade memory space and speed?

EDIT
Another test. CPU almost 0 and memory full.

Thanks

Hi @charles.collin.2

Aside from opening the file you have created with only tree assets, does opening a completely empty file also spike your CPU Percentage to 90%?

  • What is the CPU usage when D5 is closed? Can you send us a screenshot?
  • Please generate a log file, you may send it to me privately here in forum.

Yes CPU spike when loading a blank D5 scene.
