do you have multiple GPUs? I didn’t port the multi-gpu fix to Linux yet, I’ll compile the new april beta for Linux too this WE. In the mean time, did you try on Windows? I know @stephen_leger uses the Linux version and he also had problems with speed at the beginning and it’s now solved. Maybe you can also ask him? You can also PM me with files to discuss more in depth on specific scenarios.
Hi, no single (Lowend) GTX 760 but I fixed all issues with performance copying preset settings to Linux. Not all settings are reachable on Linux atm. but I am not in hurry.
I know you are a speed fan but may you remember a patch to add some wait states to the GPU to don´t block your system completely during render?
I cant find it yet at developer.blender.org.
I can render in Octane and surf the internet with some limitations without slow down render time. May a few % less.
It would be nice to have a switch for it, may GPU load High/Low or something.
Thank you for the support and for E-Cycles, mib
At least on windows, the experience is smooth connecting. What I do is to connect my screen to the iGPU to have the discrete GPU completely free for rendering. But I’ll have a look to this switch. If you find the exact differential number, it would be helpful to get it faster.
Is the cpu rendering faster with E-Cycles?
E CYCLE only works with GPU
I have reproduced the interior rendering demonstration that @bliblubli already posted a few times, but this time without screen recording overhead - 720p, 100 spp, 0.02 scrambling distance —> 5 sec render time with 2080Ti
texture and object data already cached in vram right ?
what is the result for a similar noise nevel of cycles 2.8 official
I’m on it. You provided the file 13 hours ago, I do my best. It can even take some days to get fixed. Look at this bug for example which affects many archviz scenes https://developer.blender.org/T54486. reported more than a year ago, still no fix although the BF has many devs and now very good funding. You found a scene which has problem, I’m sorry for that, but I think it’s normal to give some time to people to react. Did you ever made a bug report to Microsoft or Autodesk?
If I can’t fix it in a reasonable time, I refund you. But I used to bug fixing, most bugs I got reported got fixed in a day or two. Look here for a bug report and here for the solution and here what the same customer who experienced bugs says. A bit of patience please
So I did several test and couldn’t reproduce your noise bug. I used both the march version and the latest beta, both render with the same noise level. The noise is different (normal as E-Cycles uses a new sampler), but not higher:
Master takes 80 secs to do the path tracing and outputs this image (time is written on the line "time without synchronisation):
E-Cycles only 39sec and output this image(AI Denoiser):
This is the noisy image:
Did you use the exact same file?
Did you use the latest beta (I added a new one yesterday during the sales, maybe you got an old beta?)
I’m someone who occasionally does long renders, and am interested in this project - curious about how compatible / comparable it is to this:
here, an E-Cycles user did a comparison:
you have to download the images and zoom at 100% to see the difference.
Yes same file.
I am downloading beta again just to be sure.
Thanks a lot for showing the true speed of E-Cycles with external recording I should get such a setup too. But the slowdown of live screen recording helps some to believe.
5 seconds for archviz
so you’re using the intel denoiser? Does it still work with the nvidia denoiser?
I’m using the Intel denoiser indeed. It should work with the NVidia denoiser of course. Addons compatibility is the same as for official Blender.
about that, any news from a viewport denoiser ? both from stefan and brett?
i talked about stefan on twitter about cpu viewport denoising + gpu calculation he’s saying its possible
Hi, Brecht has answered at https://devtalk.blender.org/
The patch is https://developer.blender.org/D2862
He was not very enthusiastic about the patch but was working fine with my GTX 560Ti and GTX 760 on Linux.
May you have a look, is not that big.
Thanks for the link I’ll look asap.
