I am currently experiencing a serious issue while working on one of my projects in D5 Render. During modeling and navigation, my monitor suddenly flickers, turns off, turns back on, and an error message appears saying:
“Error: Out of video memory trying to allocate a rendering resource. Make sure your video card has the minimum required memory, try lowering the resolution and/or closing other applications that are running. Exiting.”
I have attached a screenshot of the error message for reference.
After this error appears, D5 Render closes unexpectedly. Even though I have AutoSave enabled every five minutes, the program does not seem to recover from those automatic saves, causing me to lose all the progress I have made since the last manual save.
In addition to the crashes, the viewport has become extremely slow during navigation. What is strange is that I have previously worked on projects significantly larger than this one, with nearly twice as many plants, without experiencing these issues. However, this relatively smaller project has become very sluggish and keeps crashing unexpectedly. At this point, I am not sure what else I can do.
My workstation specifications are:
- Processor: Intel Core i9-13900F (13th Gen), 24 cores / 32 logical processors
- Memory: 32 GB DDR5 (4000 MT/s)
- Graphics Card: NVIDIA GeForce RTX 5080 (16 GB VRAM)
- Storage: Kingston SNV3S1000G 1 TB NVMe SSD
- Motherboard: ASRock Z790 LiveMixer
D5 Version: 3.1.0
Windows 11
Could you PLEASEe help me identify what might be causing this issue? If there are any recommended settings, diagnostic steps, or logs that I can provide, I would be happy to do so.
Thank you very much for your time and support.
