Hi,
I’ve been working with Vray 3.6 for a few weeks now and I found that Vray causes my cpu to be active a lot more while just working in sketchup (it sounds the same as when I’m rendering an image).
I think/suspect it’s the constant rendering of the preview of the materials that’s causing this. In heavy models it causes sketchup to slow down, even to a point where there’s a bugsplat and sketchup crashes.
Is there a way to disable the constant rendering of the material (like there was in V2?)
(or any other ideas why the cpu goes crazy while just working?)
If this issue come to you just go to the task manager and click the processes tab, then check which software is using all of your processors, if SketchUp seem stable, click on “Show processes from all users” button and check which software is causing this issue.
As far as i was aware Sketchup only uses a single core (2 threads) so would never go over 25% CPU usage nativly. Since installing 3.6 i have noticed high CPU usage for a little while after switching material in the Asset library. Its like its trying to get a high quality render on the 150x150 pixel preview which is not necessary.
Personally its not caused me any major issues but i guess its unnecessary stress on the CPU?
An option to turn it off/lower the quality threshold of the preview would be awesome.
This is not something new which came with v3.6. The material preview is set to never exceed more than 50% CPU thread usage and is not a high-priority process.
The majority of users seem to prefer having detailed material previews but I’ll pass along the suggestion to add some control over its resource usage.
Like peter said its in the design of the software.
I wouldn’t worry to much about your processor running at 70-80% as long as its not causing your processor to overheat or causing performance issues on other programs. And if it is perhaps look at maintaining/replacing the cooling system. Im pretty sure the hardware is designed to run at those sorts of usage for prolonged periods of time. Id only be worried if its affecting the performance of other apps.
But on the other side, the option to turn it off in the event that it WAS causing issues could be helpfull.
What you experience is expected, as already mentioned. The Material preview begins rendering the moment you open the Asset Editor (unless there are no materials in the scene).
Hi, thanks for the response.
I just notice that it slows down my workflow and slows down sketchup compared to V2. It causes sketchup to crash from time to time (I must say I have a real quick way of working, so I guess sometimes it can’t keep up because it’s always trying to render)
I’ll have someone look at my cooling system, but it used to be no problem before so I can’t see why it would be now…
