Just so you know, there’s a 23% performance drop in d5 render version 3.1.
I’m using an RTX 5080, 9950X processor, and 64 GB of RAM.

Hi @seckinagar2
Can you show us screenshots of your test conducted with 3.1 and 3.01?
These are the results on my end:
-
3.1 Test
-
3.0.1 Test
I can confirm that there is a performance drop in version 3.1.

Hi @a.drexler
Please send us a rendering test to compare the rendering times of versions 3.1 and 3.0.1, or confirm if the issue is more related to the preview screen navigation.

This process took exactly 42 seconds in version 3.01. I need to reinstall version 3.01 to prove it to you. I have been teaching DX11 and DX12 based programs for almost 28 years. If you know of a fix, please don’t hesitate to share it. I have extensive knowledge of both software and hardware.
Hi @seckinagar2
Can you reupload the first image? It seems not to have loaded.
- We’re currently collecting feedback for this specific issue, and we require screenshots showing the difference between 3.0.1 and 3.1 rendering time
- Just to clarify, this issue occurred in all of your files and not just in this specific file, correct?
With that, can we please collect the following files:
-
Log Files
-
D5 Scene File
You may generate a link with these files and send it to me privately in the forum.
Can we collect this specific file to test it on our end? Together with your log files.
It’s not that important anymore. I won’t upgrade to version 3.1 until the performance issue in D5 render 3.1 is resolved. I’m very happy with it right now. Everything is fine for me. I’m continuing with 3.01.
