System hangs during intensive applications like Blender rendering

It's not super sophisticated. Just a test file rendering in Cycles with a lit metallic cube enclosure, a glass textured figure, and an emissive cube with some random low-friction physics for movement.

I haven't gotten around to booting the computer for a few months, but does it get that out of date that quickly? Last time I tried to do a big update pass, I got all kinds of conflicts and errors that were a hassle to resolve. Probably all the more reason for me to update more often, but I just haven't really been actively maintaining the computer much.

You are right, like always :slight_smile:

I got confused with all the computers that are standing around here :wink:
The AMD Quad-core was from 2008 :smiley: , 3770K from 2012.

Yes - this is one of the downsides of a rolling-release distribution.

I think that should have become less of an issue over recent months with the move away from “-git” packages, Transition to fixed release packages (but also Garuda isn’t a “fire-and-forget” kind of distro anyway).


Blender, although it is a free program, is rapidly upgrading and I think they are trying to compete with professional proprietary programs, that require higher end hardware. So I think that it isn't really realistic to expect that you could run it on an older/weaker computer and still use the desktop or other applications at the same time as the render. Even on a higher spec system, depending on the workload, blender can use all of the CPU.

I run a 2010 macbookpro (with a core2duo processor), but in-order to have more than one or two applications open at the same time just dosn;t work well with a full Desktop Environment.
I use a light weight Arch distro with a preconfigured window manager, because it makes the computer so much snapper. I wanted to put Garuda on it as I use Garuda KDE on my desktop. However the macbook was constantly using 100% of the CPU when I tried to use applications. KDE was just too much for it.

I didn't actually expect it to perform well. I was honestly just testing it out. The only reason I bring it up specifically is because, while other seemingly less intensive programs can also lock up my computer when used in certain combinations (Like Brave browser and Resilio Sync specifically), this one was the most easily reproducible, and it's just jarring for an operating system to become completely unresponsive at the first sign of stress rather than reserving minimal resources to maintain stability like I'm more used to with Windows. I was hoping there might be some sort of tweak that allows it to do that.

I wouldn't expect a system to just freeze without warning and then come back to responding - it kind of implies something else is going on (rather than it just being old hardware).

It will be worth updating and then trying a standard kernel, e.g. linux or linux-lts, then checking whether the latest installer images work. if so, it might be some local configuration change that your particular hardware doesn't like... :thinking:
