Thanks for the tests… But am afraid we cannot much here.

Lukas Stockner (lukasstockner97) added a comment to T59299: Recognizing too much GPU's.

Can you try running blender with the arguments -b --debug-cycles --python-expr "import _cycles; print(_cycles.available_devices())" from the command line and posting the output here?

@Alaska (Alaska) a clean install was made multiple times, with no difference on the number of recognized GPU's

Alaska (Alaska) added a comment to T59299: Recognizing too much GPU's.

I had the exact same issue. Two RX 570's reported and Blender crashes if the "false" GPU is enabled while rendering. Doing a clean install of the drivers fixed it for me.

Brecht Van Lommel (brecht) closed T53945: Blender crash after enabling GPU render on Mac. Need to restart computer before Blender can be used again as Archived.

Cycles: OpenCL on macOS has been disabled

There was a growing payload of bugs in Cycles related on OpenCL on macOS
platform, and those issues were caused by a compiler bug, which we have no
control over.

Surely, it is sometimes possible to work compiler bugs around from a
source, but we are facing some of the issues which are not solvable in this
way. Also, such solutions are usually short-living,. since adding more
features are often kicking compiler to provide buggy binary again.

In this case compiler will not get fixed since Apple decided to discontinue
OpenCL on its platform.

So the decision was made to drop support of OpenCL, keep official features
of Blender stable and predictable, and focus on things we have control over.

P.S. Older Blender releases are always available. Surely, this sounds like
using an ancient software without neat features. But we can't push Cycles
OpenCL on macOS measurably beyond that anyway.

LazyDodo (LazyDodo) added a comment to T58148: Cycles GPU rendering not working properly GTX Titan (?misses light path bounces).

there's some background on the cuda 9.1/10 issue in T56858 but as i said earlier if 9.1 doesn't work for this issue, it's very likely a different issue and we shouldn't be mixing the reports cause that'll just confuse everyone.

Alternatively, we detect this case in mesh_build_data() and don't create new pointer for an evaluated mesh.

Sergey Sharybin (sergey) added a comment to T58251: Blender ignores linked meshes when rendering in Cycles.

@Brecht Van Lommel (brecht), not sure what you mean by "the new dependency graph is duplicating these meshes". There is a single Mesh datablock, and several Object datablocks in such example.

Brecht Van Lommel (brecht) updated subscribers of T58251: Blender ignores linked meshes when rendering in Cycles.

Clément Foucault (fclem) added a comment to T58266: Bottom half of the default cube and other meshes are transparent with eevee.

I remember having fixed this problem... I think it was rB117bc96ce88474d3c6b28e669e6ee339441051fb but if this is back, that means your GPU passes through the
detection somehow.

Alessandro Tagliafierro (Aletag) added a comment to T58546: Blender closing randomly with error EXCEPTION_ACCESS_VIOLATION.

Thanks for being so quick in the response.
I tried everything you said, and I attached the error messages for the -d and --debug-gpu command line arguments, nothing really surprising by the way.
opengl32.dll doesn't seem to do much except it slows blender down quite a lot.
Every other thing you told me doesn't seem to have any effect, anyway now I know that it doesn't crash at a random time, but about after 30 seconds I open it. The same error goes again and again: EXCEPTION_ACCESS_VIOLATION

Casper van Leeuwen (casperl) added a comment to T58148: Cycles GPU rendering not working properly GTX Titan (?misses light path bounces).

Apologies, I was looking at the wrong CUDA version I think. My driver version was still 10.0 and my runtime version was 9.1. But here is the problem I have.. The driver versions are coupled with the graphics driver somehow, I can't figure out how to install the CUDA driver version to a year older version without downgrading my graphics driver to a year old version...

Paul Melis (paulmelis) added a comment to T58148: Cycles GPU rendering not working properly GTX Titan (?misses light path bounces).

@LazyDodo (LazyDodo) So just to get some clearity, the known CUDA bug you mentioned only applies to 2.80 (while 2.79 used different CUDA code and isn't affected)? And it's now up to NVIDIA to fix this? How does that go together with Blender's apparent policy of trying to keep the used CUDA version low, so older GPUs can still be used? NVIDIA won't release any fix in CUDA 9.x anymore, I suspect.

Alaska (Alaska) added a comment to T58207: Render time going crazy!.

@Brecht Van Lommel (brecht)
I've rendered the scene (it was missing textures so the test wasn't identical) and the total time of render was roughly 15 hours on my Ryzen 5 2600. I believe the issue may be on the users end (E.G. Other programs using the CPU, overheating and thermal throttling on the CPU, etc) but more testing would need to be done to ensure this isn't the case. I'll leave this task with you.
