I’ve just had a crash using PL9, which is unusual for me, it’s the first one I’ve ever had on my laptop. I’ve not been able to reproduce it, yet, so I’ve not reported it to DxO. Thought I’d describe what happened here in case it helps others.
I had an AI mask to raise the exposure of some dark bits if the image. No problems doing that, or then applying square crop. it was when I tried to zoom in using the std two finger gesture on this laptop’s touchpad that the error popped up and PL9 locked up.
Well nearly locked up, I was still able to get to Edit|Preferences, where I unticked ‘use DeepPRIME rendering’. OKing out of that seemed to restore PL9 but when I tried to carry on and export the image it ran very slowly, suggesting it wasn’ting using the RTX 4050 GPU.
Back in to Edit|Preferences where I found PL9 had lost all knowledge of the RTX 4050 GPU. Fair enough, the error message was clearly a GPU failure. However, a simple restart of PL9 was not enough for PL9 to re-find the 4050 GPU. It was only after I restarted the laptop that once again PL9 found, and used, the 4050 GPU.
Presumably, a restart of PL9 was not enough to clear something left in the background, though I couldn’t see anything obvious in Task Manager.
If I can reproduce this crash I wil report it to DxO. Meanwhile, I will leave the ‘DeepPRIME’ rendering disabled. A sensible thing to do anyway as the 4050 GPU only has 6GB VRAM.
Yes, all up to date. I’m pretty certain the crash was because trying to zoom in with DeepPRIME previewing enabled pushed the VRAM requirement beyond what was available.
It was the need to restart the machine in order to get PL to refind, and use, the 4050 GPU again that surprised me.
Why GPU usage to 95% or even 100% and power consumption to max would lead to a crash ?
All my rendering applications run at 100% for days or weeks sometime (unless temperature is too hot and GPU regulates this by lowering frequency) without any crash. And with several graphic cards per station working on the same job. Hardware is able to run 100%. *
Most important here is gpu temperature.
*EDIT : correct hardware is able to run 100% (which means adapted power supply and cooling system).
Yes. Some applications deal with this like that - crash when memory out - (complex physic simulations for example). But this should not be the case for photo editing softwares.
But does your system equate to the one I was using, Core i7 (13th Gen), 16MB RAM, notebook RTX 4050 6GB VRAM? That’s below the min VRAM requirement. That’s why I’m fairly sure my crash was because I asked PL to do something that the hardware couldn’t deliver, i.e. zoom in and at the same time render with DeepPRIME.
I only started this thread to tell others that the ‘fix’ for my crash required a complete restart of the laptop, not just a restart of PL.
I never expected PL to freeze from zooming in and out after the image had already been successfully rendered.
So, I tested it with a large image and pre-defined AI masks that had already pushed my computer to its limits …
