How to Fix the Low FPS - (comparison)

[3dteam]

Hello,

I’m currently facing problem with the low FPS when opened some work files, I tried to turn on “FPS Booster for Complex Geometry” and “Super Resolution” but it didn’t change anything, also I tried to not open any tabs files but it doesn’t work.

Here’s the problem and comparison when I try to open it using different PC which I thought have the ‘almost the same specifications’ (Correct me if I’m wrong about this), here I’m using same work file:

1. The first picture is showing the D5 render’s statistics, the VRAM, and system information ( 32G + Intel Core i7-14700F + NVIDIA GeForce RTX 4070 Ti )
2. The second picture is also showing the D5 render’s statistics, the VRAM, and system information ( 32G + AMD Ryzen 7 5800X + NVIDIA GeForce RTX 4070 )

Please enlighten me about this comparison, does the different CPU has the biggest impact onto this issues? Or can anyone tell me how to increase the low FPS and to fix this issue.

Thank you.

In images 1 and 2, I noticed that the CPU, RAM, and VRAM usage is significantly higher compared to image 2.
Are the graphics card drivers on both machines the latest version?
I think the difference in Windows versions also contributes to this discrepancy.

Windows versions also contributes to this discrepancy.

Hi, yes i noticed that too that the PC01 usage are higher than PC02 even tho PC01 opened less tabs than PC02. As you can see from this picture, the PC01 use the latest version of the graphics card meanwhile the PC02 not updated yet but can run faster. If the windows is the issue, so it means that the windows 10 is better match with D5?

Please if you know why the PC02 can run faster even tho PC01 also almost has the same specs.

System Requirements for D5 Render | Hardware test

D5 Render adopts real-time ray tracing technology, which has minimum requirements for graphics cards and system configuration. When D5 Render is launched for the first time, it will automatically check whether your computer meets the minimum requirements. Please upgrade to GTX 1060 6GB, AMD Radeon RX 6700 XT or more powerful options. D5 Render’s real-time raytracing technology is built on DXR of Windows systems, and the current graphics cards that support DXR can be checked on RTX & GTX sup…

Personally, I have used D5 on both Windows 10 and 11, and my experience suggests that Windows 10 provides a better performance. Since then, I’ve been using D5 exclusively on Windows 10. Currently, I’m not sure if D5 has been fully optimized for Windows 11, so I recommend reaching out to the D5 Render admin team for clarification.

There are already some posts on the Forum discussing this issue, and the D5 admin team has also confirmed that Windows 11 is not as good as Windows 10.
However, those posts are quite old.

In my opinion, you should just use them for reference. For accurate information, it’s best to consult the D5 admin team.
Thank you!

Oh I see, so there’s already a concern about it. Hope the admin team can help us and find the solution.

Thank you for the help.

Hi @3dteam thank you for sharing a detailed description of this issue and we sincerely apologise for the inconvenience. Have you checked the FPS status on empty scenes as well?

Could you please confirm the version of Win10 and Win11 on PC1 and PC2 respectively. To further troubleshoot this, could you provide us with this scene file as well as the log files from PC 1 and PC2. D5 Support Tool - Get Help / Tech Support - D5 RENDER FORUM

We can also see that the VRAM usage is quite high on both devices, and in this state your GPU has become unstable. I recommend that you also update your graphics card drivers for compatibility and better performance in general. Many thanks
