Thanks for your time and this info.

Thanks for the fast reply. So in my scenes there are hidden Blender material trees? Because I can't find them. Or is the scene "bugged"?

CPU and GPU are rendering different results. Here's the comparison.

Here's again the scene I used for the above video with the settings (1024 samples). The former upload was an older scene with different settings. Just to get sure.

Yes, it's not a Denoiser issue. My above rendering isn't using the Denoiser and a sampling rate of 1024. I have an older video of the same scenes without artifacts but I can't say what build I used for it.

Michael Klein (Renderbricks) added a comment to T56902: Scene with 71K LEGO parts to support improving Blender 2.80 performance +++ will freeze Blender 2.79 when using Outliner.

Here's a workaround to bring back performance after using "Make Dupli-Face". In case I would like to animate all bricks this is not a solution but to build massive static objects and environments like a city. I would love to see an overall better handling of my attacked scenes of course ... in the future.

It's not resolved in aa844ad676d from today. The CUDA error still exists. Viewport works. First render after fresh load will just render CPU tiles but GPU tiles keep empty. Second try will give a CUDA error. I also had again a Blue Screen. But not everytime.

Michael Klein (Renderbricks) added a comment to T44643: Cycles rendering, packed images render differently from unpacked.

Here's the scene with the issue. The original non-packed scene renders fine. In the node-tree the textures "apple_roughness.png" and "apple_normal.png" are set to "non-color". But when packed the "Color Space Setting" in the "Data-Blocks" is set to sRGB. Setting to "Non-Color" will fix the issue.

I found the issue. In Data-Blocks the Color Space Settings of the non-color textures is set to sRGB. Setting them to Non-Color will fix the issue.

Michael Klein (Renderbricks) added a comment to T53902: Packed Scene with Textures will be rendered wrong.

I don't know it this helps but if I open an image editor and manually set the color space of both the normal and the roughness maps to "Linear" instead of "sRGB" the packed version also renders fine.
Seems to ignore the non-color data setting of the image texture nodes.

The attached simple scene seems to work with the latest release. But keep in mind that I also could render this before but later the error appeared. Maybe its a random error caused by a specific situation?

Michael Klein (Renderbricks) added a comment to T52625: CPU render will look different to GPU render and fails randomly.

You can remove the bevel node on those materials if you want to verify it. To me it looks like specular highlights from bevel blurred by depth of field, which can be quite noisy.

Michael Klein (Renderbricks) added a comment to T52625: CPU render will look different to GPU render and fails randomly.

From profiling this looks like a performance issue with the OpenImageIO texture cache and .hdr files, the workaround would be to save the background image texture as a .exr file.

The render differences look like they're just bevel differences, there can also be some differences in image texture filtering when rendering with OSL.

Render on cpu:
Start normal, didn't finish because of the long render time it would naturally a 2K image would take, so i canceled the render.
Render on Gpu:
Starts and renders and denoises, there is evident difference on the edges but couldn't notice anything particularly different.

Maybe a developer notice it right away or maybe a simpler smaller example its needed to test, not sure.

Michael Klein (Renderbricks) added a comment to T52360: CPU slow-downs extremely but speed-ups when moving render window.

OK. What I do now . I start the render and zoom in. When I zoom out the tiles slow down and the estimated render time is over 12 hours. When I zoom in at a maximum the tiles speed up and the estimated render time is now 5 hours. Looks like this is a fair workaround. :-)

Hi Brecht,

Michael Klein (Renderbricks) added a comment to T52360: CPU slow-downs extremely but speed-ups when moving render window.

No. That's not the point. Watch my recoreded video and you will see that the speed of the tiles in the transparent areas slow-down extremely. When moving the window they start to render in an expected and correct speed. It's not correct that the tiles will take ages in the transparent area. The same issue you'll have randomly in the areas with geometry. When moving the window the rendering speeds up to the maximum speed. When minimizing the window the geometry area seems be rendered efficiently till it comes to the transparent area. The slow-downs and sometimes freezes of tiles is not normal.

Michael Klein (Renderbricks) added a comment to T52275: Denoiser will blur sharp reflections.

I found an interim solution by using Branched Path Tracing. This looks much better. I could also set just Glossy higher and turn Indirect off in the Denoiser. But just using Branched works good actually.

Metallic and black color (no diffuse) is working fine. Specular and SSS with more diffuse will cause a blurred result.

Michael Klein (Renderbricks) added a comment to T52275: Denoiser will blur sharp reflections.

Thanks for your detailed answer. I rated this as a bug because the floor reflection is correctly sharp while the wall reflection is sharp in the render progress and will be blurred extremely by the denoising what will falsify the result.
