SketchUp using all cores off the processor!!!

When I was referring to the architecture of SU I didn't mean the programming language they used, but how they structured their code and inner working.

Btw, Didn't I read elsewhere here that is may not the high polycount that is the problem for SU, but the way textures are handled?

Textures does slow it down, but even with plain default materials SU will bog down with high polycount.

It's most likely a compound of causes for it.

So this older program I have uses this command called +fullproc. It's supposed to make the program use all cores or threads. I wonder...

I doubt it. Programming to use multiple threads or cores effectively requires techniques to split up the workload into pieces that can proceed in parallel and to synchronize the results afterward. This is far from easy or automatic, and is not even possible for some kinds of tasks.

Ok so bottom line, no multithread support in the next year or so ?

It's astonishing that even with a Core i7 3.9GHZ 4C/8T, PCIE SSD , 32GB of RAM and GTX 780, I have to wait 5 hours to clean up a 110 MB high details file because my CPU usage is 15% at max while rendering the scene at very high details takes 4 hours.

Also with complex models, I get a lot of hiccups and sluggish performance and it's definitely not my Nvidia as GPU-ID reports 10-20% GPU usage while sketchup is freezing or not responding most of the time with 15% CPU load ( the maximum it can use ).

I'd swear by sketchup if it were multithreading.

What process are you doing that you wait 5 hours? CleanUp plugin or ..?

What? So to be clear: You hit a scene and wait 4 hours to see it on the screen. Or is this for some sort of output like pdf? Until it gets faster, break up your files. If it's details, why put them all in one file?

Hiccups. Yeah the autosave for large files is a pain. As someone noted regular save is relatively fast, so why is autosave slow?

Hello and thanks for your reply; Yes the cleanup plugin takes too much time. Not that I am trying to compare sketchup to Autodesk products but Autosave usually doesn't lag me that much as I'm on a PCIe SSD ( 800+ MBps read/write ) I hit save as and it takes 2 seconds to save a 150MB sketchup file.

It's not only about the cleanup. For instance if I want to import and obj file using Simlab plugins sometime it takes 20-30 mins depending on the file size because only one thread is active out of 8.

I understand that OBJ files can be complex but after cleanup they shrink significantly.

Here's an example of a scene I'm rendering with sketchup ( needs 14 hours to finish ) :

Before cleanup file size was around 350MB then it went down to 74MB but it took literally 20 hours to finish the cleanup.

Looks like that's going to be a nice render!

Not that this is going to save you tons of time, but I only use CleanUp as I work, only on select parts of the model, nothing too big.

That's too long!

Frame your model nicelly and save. Then turn off thumbnail generation on "Model Info".

I understand that but if you need your render to look nice you need to import some complex models ( flowers, vase, figurines etc.. ) and these really hit sketchup hard. Check the remaining time for just merging faces :

I just said that with my SSD AND without thumbnails, I don't get 2 secs saves. I don't even notice saving anymore.

You should use proxies for that sort of stuff.

Merging faces is not saving a model, it's a complex face operation like explode or import.

My problem is not the rendering, I can render relatively quickly. But the problem with Sketchup itself.

I have been trying to load a 118 MB skp file into sketchup but it took over 6 hours. What's funny is that 3DS Max could load it in 2 mins.

We can't deny that Sketchup is slow, really slow and I refuse to leave it for basic modeling as it has a lot of potential to compete with the big 5 but then we need a major update.. maybe a complete re-written Sketchup.
