thanks !!

Hi there,

I apologize for the inconvenience this issue has caused. Are the FPS Booster for Complex Geometry and DLSS 3.5 enabled? Also, can you provide me with the following information?

thanks for your answer, here are the requested informations.




I have two GPU, I guess that why D5 render think i use only 30%. I saw 90% on the main gpu at the same moment.
Do you know if it possible to reduce the resolution of the real time render ? (adaptative scaling is off, when its on : fps decrease) . Super resolution is on, booster fps is on and complex geometry is on

THanks for yours advices

Hi there,

Thank you for providing the following requested information. There seems to be nothing out of the ordinary regarding your VRAM Consumption aside from:

  • GPU Utilisation at 94% since anything above 80% will cause some crashes and lags. But there are instances where it is unavoidable. I do suggest optimizing your file by hiding assets that are not seen in particular scenes.
  • Dedicated GPU has only used 4.7 GB out of 8 GB which is high and should not have a “laggy” experience.
  • A 16 GB laptop RAM may be limiting while working with heavy files but as for now, it may not be an issue.

As for your question regarding whether it is possible to reduce the preview quality to maximize performance, you can enable “Smooth Mode” which is located in your display settings.

You may also want to try to disable your other GPU (Intel) and see if the “Statistics” being displayed in D5 Render will coincide with the results from your Task Manager. And also if there are any differences when it comes to the FPS. You can enable it again if there are no differences, please let me know of its results.
