System Information
Operating system: Win 10
Graphics card: 3070 RTX new drivers installed.
CPU : 5800X Ryzen
Blender Version
Broken: 2.93 Optix + CPU option
Worked: 2.92 because it doesn't have this option. Optix alone works well
I have attached the file, Please simulate at least 3 frames.

@zrp Please attach your full system information to your report by uploading the file saved by Help > Save System Info in Blender.
When you are referring to "OptiX + CPU", do you mean the OptiX denoiser (Render Properties > Sampling > Denoising > Render > OptiX, as is it enabled in your file) or the option for GPU rendering in Edit > Preferences > System where you have a CPU activated as well?

Please open Blender's installation directory and double click on the
blender_debug_gpu.cmd
. This will start Blender in debug mode and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located inC:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt
(or simply type%TEMP%
into the path bar of the Windows Explorer).Hi, @rjg
The one in preferences.
system-info.txt
I kinda failed to make blender crash*. Sorry if its the wrong term, but it hangs in the same state as my previous screenshot. It keeps adding up the rendering time in the information as I have highlighted top left.
As u probably notice, it keeps going on and on and doesn't seem to stop for this simple scene.
EDIT: I think I have an older file which is related to the same project name. Ill upload that here >>>
crash_2.93.crash.txt
I managed to crash, but this time when on viewport. A CUDA error. blender_system_info.txt
blender_debug_output.txt
This file is a different project. Its a very heavy file with the smoke simulation. I thought this might help to track down?
Cheers!
crash_2.93.blend
This one should be easier for you because now blender won't let me open the "blender_debug_gpu.cmd" file anymore. I really crashed it for good.
To replicate the same,
blender_debug_output.txt
blender_system_info.txt

Hi @zrp, can you still reproduce it on recent Blender versions (3.1.0, 3.2.0)?: https://builder.blender.org/download/daily
I don't have similar system to test myself. If problem persists I'll ask someone to check.

blender_system_info.txt
Can not reproduce a Crash with either Blender 2.93 or with Blender 3.1.
Also not on a RTX 2080Ti
Added subscriber: @Baardaap
I tried that last .blend (linux, RTX 2060 SUPER) and can't get it to crash. With Optix + cpu (intel) enabled.
But it's also not completely clear to me what the steps to reproducte are. Should I also do the smoke sim bake?
Added subscriber: @iss
After baking smoke, it spent about 5 minutes just in denoising stage with 2.93
Don't see any issue with 3.2
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.65
Also no crash with another provided file and steps
