I am having a big issue with high VRAM usage on my project and I can’t seem to figure out what is causing it. My current setup is an Intel 12900K processor, 64 GB DDR5 RAM, and 4080 super (16GB) graphics card and the model is being livesynced from Rhino 7. I do have alot of heavily detailed interior blocks (imported) so my initial thought was to reduce the number of mesh faces in some of the heaviest blocks. Ironically enough, after optimizing several of these blocks and eliminating 59,000,000 faces from the project the VRAM usage actually increased by ~6% but the FPS also increased by ~4FPS which makes no logical sense. Here are the statistics prior to optimizing the blocks:
Just to clarify, I did save the project, close out of D5 and reopen it to before checking the statistics post optimization. Nothing I do seems to have any effect on VRAM usage and I have no idea if the imported model is the culprit or D5 assets? Even if I hide every asset in the scene the VRAM usage doesn’t change more than 1%. I’m completely stumped and and getting increasingly frustrated over the constant mystery of how D5 uses VRAM. Other people in my office are also experiencing similar issues. Any help with this would be greatly appreciated.
I apologize for the inconvenience this issue has caused. Can you please send me the following information?While running the current D5 File that you were pertaining
You may want to try the following steps to Optimize Graphics Memory Usage:
Start D5 Render with administrator privileges and restart your computer. The program will automatically modify the TDR values, which can improve the stability to a great extent.
Turn on DLSS.
Depth of field, Tyndall effect, and other settings can take up a lot of video memory, so use your discretion.
Higher resolution mapping will also take up video memory, you can replace the mapping of materials farther away from the camera with a lower resolution mapping and try to avoid using replacement.
More reflective scenes will reduce efficiency, you can turn the specular of materials far from the camera to 0 to cancel the reflection.
Windows’ own GPU usage data may not be accurate, we recommend using GPU-Z. Check the sensor-memory used parameter for better memory management.
