I recently upgraded my GPU from an NVIDIA RTX 3060 Ti to an AMD Radeon RX 9070 XT, expecting better performance in D5 Render. However, I’m experiencing significant slowdowns when loading files and during the rendering process. The overall performance is noticeably worse than before, which is quite unexpected considering the hardware upgrade.
I’m wondering if this issue is due to differences between NVIDIA and AMD GPUs, or if it could be related to a specific driver problem. Has anyone else experienced similar issues with AMD cards, particularly the RX 9070 XT, in D5 Render?
Any advice or solutions would be greatly appreciated.
I apologize for the inconvenience. Indeed, there shouldn’t be any performance issues with your recent upgrade. Does this occur in all of your projects?
Thanks for the response
Right after the upgrade, I formatted the hard drive and installed Windows 11. Then, I updated all the drivers to the latest versions(25.3.1) using AMD Adrenalin Edition.
Which version of Windows 11? Is it perhaps Windows 11 24h2? If it is, can you try reverting to a previous version and see if it affects any performance issue?
Also regarding my previous question, this issue is evident on all of your files?
Yes, I’m running Windows 11 version 24H2. However, I had experienced similar performance issues even when I was using Windows 10 with the same hardware setup.
Also, the same problem occurs across all my project files, not just one. So it doesn’t seem to be a file-specific issue.
Just in case it helps, I’m attaching the results of a 3D benchmark test as well.
Thank you for providing this detailed information. I have forwarded this issue to our development team for further investigation. Please note that on our website, the RTX 3060 Ti is listed as a ‘Recommended Requirement’ for D5 Render, and we generally advise using RTX GPUs over AMD GPUs. https://www.d5render.com/post/system-requirements-for-d5-render
In the meantime, you might consider reverting to version 2.9.1. The 2.10 update introduced Path Tracing, which can significantly increase GPU load.
How large is the power supply, did you upgrade it as well? Besides, make sure D5 Render uses the RX 9070 xt gpu, not the AMD integrated graphics, your monitor should connect to the GPU, not the CPU.
If the problem persists, please show us the FPS in D5 Render, also describe more about the performance drop behavior.
Yes, I upgraded the power supply to 850W to match the new setup. The monitor is properly connected to the GPU, not the CPU, so that’s all set.
The main issue right now isn’t about FPS after the scene is loaded—it’s that D5 Render takes an unusually long time just to load the file. That initial loading time is the bigger concern at the moment.

Unfortunately, it’s all same on version 2.9.1
Hi. I did upgrade my GPU to a 9070xt. It was a clean install of Windows 11 and everything was running fine. I saved my file played some games and when I returned the file took ages to load and kept crashing. I logged out of D5, started a new project and for some reason that allowed me to re-open my project. with no issues. It’s a slightly different issue to the OP but I thought it might be worth trying to log in and out to see if it helps.
After you have reinstalled and launched D5, please note that the first launch will be very slow because it needs the GPU to compile the shaders. After that, * * D5 should launch normally
Note: We recommend saving your project files to various storage locations and creating backup copies to ensure data safety.
I tried the process, and while the loading time has improved, the overall performance is still extremely poor. Using the same project files I previously worked on with the RTX 3060 Ti, the render time was more than four times longer with the RX 9070 XT. Even after opening the files, the viewport performance and reaction were so slow that it became almost impossible to continue working.
I’ve been having this problem ever since I bought the RX 9070 XT. It seems to be some kind of issue with the GPU memory, because even though it takes a long time to load projects, once it does and the program is “fresh,” everything works fine. But after about 40 minutes, performance starts to plummet, making it nearly impossible to work with the program.
I already mentioned this problem here months ago, and we’re still in the same boat. It makes D5 unusable. I did everything that was asked here—I sent the log, provided all my PC’s specs—and nothing changed. No solution.
It doesn’t matter what power supply I use, how much RAM I have (I have 32 GB), what processor I have (I have the 5800X), or what version of Windows I’m running (I use Windows 10).
Right now I’m working on another project and facing the same old problem. It’s clearly a memory-related issue, but after MONTHS of dealing with the same problem and several major program updates, if the issue persists, it’s obvious they don’t know what the problem is.
To give another example, Twinmotion, with the same visual load and the same hardware, doesn’t have this issue, nor does Lumion, nor do other engines within 3ds Max like Corona or V-Ray.
