TDR issues, changing registry editor not working

[placroix]

Hello,

We are experiencing issues with low TDR (Timeout Detection and Recovery) since the 2.9 update.

We updated the drivers for an RTX 4090 graphics card and attempted the following manual fixes, as suggested here:
How to solve Timeout Detection Recovery problem when rendering.

Before the update, everything was working fine. Since the update, we also tried the automatic TDR fix proposed by D5, which restarts the computer and changes the setup.

However, in both cases, when we try to load large files, the system crashes after approximately 20 seconds without any error message.

We are faced with two scenarios:

1. If we keep the original setup, the file fails due to low TDR.
2. If we apply the manual fix, the file crashes after 20 seconds, and we can’t pinpoint the cause.

Do you have any suggestions for what might be causing this issue?

Thank you,

Pascale

Hi there. I apologize for the inconvenience this issue has caused.

• These issues are only evident when you try to load a large file, right? Or does it persist even in other files, big or small?

• Have you tried updating your graphics card driver? If not, please try to update it to the latest version.

• Can you also send me your system information, VRAM, and Memory Speed?

Hello,

We have already attempted updating the graphics card driver.

While some large files load successfully, others continue to encounter TDR-related issues. Implementing the TDR fix prevents the typical TDR error from appearing, but the software still closes unexpectedly. We also adjusted the registry value to 120 as a potential solution, yet the software continues to close without displaying an error.

Please let us know if there are any further recommendations for addressing this persistent issue.

Thank you.

Hi @placroix

Sorry for the issue and want to know more details.

• Were any of these project files functioning correctly in version 2.8 before they started reporting errors in version 2.9?

• Did you upgrade the driver version recently? What’s your last driver version? Could the issue arise after updating the driver version?
