D5 render 95% VRAM usage at all times - Crashes program

Hey! So I started using D5 recently and while I love it I found it quite unstable with it crashing regularly. I noticed that I have 90-97% of VRAM usage at all times no matter what I do (if I create a new file it sits at 30%ish but as soon as I start adding stuff it spikes to 90-100% no matter if I turn everything off or if I switch to the performance quality setting), even if I turn everything off. I have an RTX 5080 16gb VRAM and 32gb of RAM. I have the latest Studio Drivers. What am I doing wrong? Super Resolution and all those DLSS options are enabled. I need it to work more smoothly. Thanks!

Hi @mpindur

Just to confirm, the crash and significant slowdowns are they evident even on empty D5 Files?

  • If you haven’t tried it, please open an empty D5 File and try navigating around it. You’ve mentioned that adding some stuff significantly increases VRAM usage. Is this from D5’s statistics or from your Task Manager?
  • You may also open Residence Lawn to test how it behaves

You may send us a video recording showing the issue.

We also recommend the following:

  1. Ensure that D5 is utilizing your RTX 5080 GPU by temporarily disabling the Intel integrated card.

  2. Try a clean reinstall of your drivers

  3. Ensure that D5 is set at High Performance in NVIDIA Settings.

  4. May we also know the model of your laptop? You may check the built-in application to set the power mode.
    – Example: ROG = Armoury Crate

Hey! Thanks for the reply, so I recorded a few videos so you can better see what is going on. These are Onedrive links, since I dont know how else should I share videos:

DEMO 1: high vram use demo 1.mp4

DEMO 2: high vram use demo 2.mp4

These are 2 examples of projects Im working on, there are many more and this high vram usage happens in all of them. You can see in those 2 videos that the vram usage is constantly between 90-100%. Even if I turn ALL layers off and nothing is on screen, the VRAM remains at 90%+.

HOWEVER, I’ve also experimented with that Residence lawn scene and a new file, and found that VRAM is not high there, in the residence lawn file, VRAM stayed at 30%ish and in a new file it stayed at the same value more or less.

NEW FILE: blank file test.mp4

Even if I added the same sketchup model from the 2nd demo video I shared, the VRAM stays low. This is extremely weird. Because when I removed all assets by turning off the layers in the high vram usage file, the VRAM did not go down. But here, in a blank file with the same 3d model, the VRAM stays low.

And this is not a single case, this happens to ALL my files and projects. They may start with low VRAM usage but eventually they go up to 90%+ VRAM usage.

I’ll attach these 2 projects here in Onedrive links so you can have a look and maybe find what is wrong with them?

Project 1: Project 1

Project 2: Project 2

And to answer your other questions: 1. Ive tried this, no change. 2. I also tried this, I even switched betwen the Game Ready and Studio Drivers, no change. 3. I tried this, no change. 4. The laptop model is a MSI Vector 16 HX AI A2XWIG

Thanks!
