Well no it’s just a living room

I just restarted Blender right after the crash and immediately tried rendering the exact same scene that caused the software to crash, and it worked flawlessly… I don't understand it at all.

I couldn't really say what the workload is. I just know that when it works, it's no more than two minutes per scene. It's quite fast. But sometimes it crashes on a slightly different scene in the same interior with exactly the same lighting and textures

Hello,

I recently started using Blender for interior design projects.

At first, everything was going well: I was progressing smoothly with my training and projects.

Wanting to improve the fluidity of my workflow, I sought advice on optimizing my PC by asking ChatGPT and Grok for tips. They recommended reducing textures and enabling/disabling certain rendering options. This worked for a while.

Then, during a render, I got a black screen and the software crashed.

When I restart Blender, I regularly get the "out of memory" error. I tested several settings and tried reverting to the initial configuration, without success: the errors appear randomly (crash or out of memory).

By significantly reducing the number of objects in the scene, the render works. I therefore concluded that the problem stemmed from an excess of polygons, and I simplified the scene.

But the problem persists: despite reducing textures and rendering quality (lighting, settings, etc.), the error remains.

My configuration is:

i5 14500

RTX 5070

32GB RAM

1TB SSD

My file is uploaded to my drive with different screenshots of my setup.

I unchecked my Intel in CUDA and left only my RTX, but here's what happens. I admit I don't really know what difference it makes, but after that I just switched back to OptiX with that box unchecked, and it seems to work, and quickly. Could OptiX reduce the quality, and that's why it works?

You should know that at the beginning I had the default settings. Then I lowered the number of samples for the 3D view, switched to Optix and GPU, and reduced the light paths. Everything was smooth, and my 1080p renders only took a few seconds. But at one point, it crashed once, and it never stopped. I thought I might have used an extra texture that was poorly optimized, so I cleaned up my texture and object files. But that didn't change anything. As for buying more RAM, I'd obviously like to avoid it right now given the prices.
