D5 Render freezes during rendering and sometimes crashes the whole system

Hi everyone,

I’m having a serious issue with D5 Render that makes it very difficult to work, and I’m hoping someone here can help.

The problem occurs when I start rendering. Sometimes the render completes successfully, but very often D5 Render freezes during the process. In some cases, the program doesn’t just hang — it completely freezes my entire computer, forcing a hard reboot.

I’ve tried many different approaches, but so far I haven’t found a solution. Initially, I was getting TDR-related crashes. I changed the TDR settings in the Windows registry, and since then the program no longer crashes immediately because of TDR (at least I think that part is resolved).

However, the current behavior is that I start a render, wait and wait, and:

sometimes it finishes,

sometimes it just freezes indefinitely,

sometimes it locks up the entire system.

There’s no clear pattern, which makes it very hard to diagnose.

I can send my system configuration and log files for reference.

At the moment, it’s basically impossible to work reliably like this, so I would really appreciate any help, suggestions, or ideas on what could be causing this and how to fix it.

Hi @martynamiaarch

I apologize for the inconvenience caused. To help us investigate further, could you please provide the following:

  1. The render resolution and render settings when the freeze occurs (e.g. 8K/16K, GI on/off).
  2. Whether this happens with all projects or only specific scenes.
  3. Approximately how much GPU and system RAM usage you see in Task Manager when the freeze happens.
