Also when I render to a new window or render in the view port with cpu. cpu usage never reaches 100% stays around 75% when rendering to new window. Stays around 25% when doing view port rendering.

Cores are set to automatic and shows 40 cores.

Does 2.72 work? Does a daily build work? https://builder.blender.org/download/

Have not tried it with 2.72. The video card that is having the error is a GTX 970, on my new machine, and is only supported with Blender 2.73. I am using a GTX 760 with 2.71 on my other machine.

If I open a new scene, set to GPU with the GTX 970 it will render the default cube. It is just crashing with the project created in 2.71.

I get same error with daily build.

Update:

Two things were making it crash. HDRI files as environment texture. Also, i tried to render my IES lights with the IES add-on. That made it crash as well.

Also crashing in experiment mode with my true displacement material

Then it would be helpful to upload the file(s) that crash.

Not sure how to upload files. Pop up says to drag and drop into comment window. But that does not seem to work.

Thomas Dinges commented

2015-01-21 08:21:53 +01:00

Then try a site like pasteall.org.

@AaronSmithey, you can use ftp://ftp.blender.org/incoming/ to upload hte file or mail to sergey.vfx AT gmail.com.

@AaronSmithey, we really can't fix issues we can't reproduce without collaboration from those who're experiencing this issues..

Hi,

Sorry I have not responded. I am really swamped with deadlines at the moment. Regarding the IES lights, the ones that were in the 2.71 file were not working in 2.73. But when I deleted them and replaced them in 2.73, they worked fine. So I think the only outstanding issus are the true displacement material not working in experimental mode and HDR not working for me. I need to test it with 2.73a though.

Thanks for all you do,

Aaron

I have tried the true displacement material in experimental mode with my GPU and it works in 2.73a. But the HDR still crashes. Everything works fine on CPU. I will send you the test scene.

What is the user and password to load to the ftp?

Sergey Sharybin commented

2015-02-03 18:10:25 +01:00

Anonymous access should work i think.

Test scene has been loaded.

I moved the file to http://download.blender.org/ftp/sergey/bugreports/T43338_Test%20Scene%20From%20Aaron%20Smithey.zip (files in incoming are getting automatically removed when they're 2 weeks old).

Now, about issues you're having:

I can not confirm low CPU usage when rendering viewport and to the new window. After the synchronization process is over (which is indeed not fully threaded) path tracing uses all my cores. Did you try limiting threads manually to say 20 (so all real cores are used, no HT), or 32 (just nice round number)?
It's a bit unfair to compare rendering 2.71 with gtx760 and 2.73 with gtx970.Please confirm/bust this myth: "rendering the file with 2.71+gtx760 works fine, rendering the same file on the same machine with 2.73a+gtx760 runs out of VRAM".
True displacement material had a bug in 2.73 and it is now fixed in latest builds from builder.blender.org and in 2.73a as well.
