Sudden performance drop and high VRAM usage in D5 Render

Hi,
Recently I’ve been facing significant performance issues in D5 Render. The program has become noticeably slower, and VRAM usage constantly spikes to 100% even when working with scenes that used to run smoothly before.

I tested both NVIDIA Studio and Game Ready drivers — no improvement in either case.
Previously, the same scenes opened fast, ran stable in real-time view, and exported videos without lag. Now even small actions introduce severe slowdowns.

Here is my system info:

  • D5 Render Version: 2.10.1.0579
  • GPU: NVIDIA RTX 2080 SUPER (8GB VRAM)
  • Driver Version: 32.0.15.7652
  • CPU: Intel Core i9-9900K @ 3.60GHz
  • RAM: 64 GB
  • OS: Windows 10 Pro (Build 19045)

Any suggestions or fixes would be appreciated. Let me know if you need logs or additional data. Thanks!

Hi @mailham

I apologize for the inconvenience. I have some few questions for clarification:

  • Which version of D5 was used when you have observed that these scenes were running smoothly compared to now?
  • Is this evident to all of your files? Or is it file specific? Have you tried an empty file or perhaps a demo scene file?
