Issues with latest R8 and D5 render

Hi McNeel Team,

I am new here in the forum, but have been using Rhino since 2015.

I recently updated to the latest Rhino 8 version along with the latest D5 Render update. Unfortunately, I’ve encountered several significant issues that have affected my workflow, forcing me to roll back to version 8.5 (the last version I had in my download folder).

Here are the specific problems I faced:

  1. Extremely Long Sync Time: Syncing between Rhino and D5 Render took an excessively long time. Previously, the sync process was relatively quick and seamless.
  2. Rhino Mapping Not Showing Correctly in D5: The mappings I set up in Rhino did not translate correctly to D5 Render. This mismatch caused significant disruptions, as the visual representation was crucial for my project.
  3. D5 Render Very Laggy: Performance in D5 Render was substantially degraded. The software became very laggy and unresponsive, making it challenging to navigate and render scenes.
  4. Rhino Laggy as Well: Not only was D5 affected, but Rhino itself also became noticeably slower and less responsive after the update.
  5. Running out of memory. I am running out of memory on my graphicscard (AMD Radeon RX 7900 XTX - 24GB GDDR6 RAM) which has never happend before (even this morning it was running smoothly).

After rolling back to version 8.5, all these issues were resolved, and both Rhino and D5 Render worked perfectly as before. Given this experience, it seems there might be some compatibility or performance issues with the latest update. I don’t know if it is on your or D5’s end…

Could you please look into these problems? I would love to continue using the latest version with its new features, but the current performance issues make it unworkable for me.

Thank you for your assistance.

Best regards,
Simon

Hi SOS,

I’m going to send you links to each version 8.5, if you can upgrade until the issue presents itself would help narrow this down. We may need a file at some point as well.

Hi @Japhy,

Thank you so much for sending the versions. I have been running through the different updates and during testing for about 1,5 hours. I have for each version opened two different rhino files and launched one of them into D5. After it has been launched i have been spining the model(like when working in 3D) for a while to check what happens.

Here are the results:
Rhino - 8.5: Working
Rhino - 8.6: Working
Rhino - 8.7: Working
Rhino - 8.8: Running out of memory after about 5 min of working, and crashing.
Rhino - 8.9: Running out of memory after about 5 min of working, and crashing.
Rhino - 8.10: Running out of memory after about 5 min of working, and crashing.
Rhino - 8.11: Left my PC for about 8 min while Lauhing d5, when i came back it had an error saying I was out of graphic memory and crashed.

So from 8.8 my pc is using A lot more VRAM. It keeps building up the ram usage until it crashes after 5 min, even if i just leave the pc it will keep building up the ram usage and eventually crash.

I hope this is a help for you to finguring out the problem :slight_smile:
