Vulkan Device Error while working with Blur TOP

Bugs

Hello,

I’m having trouble with a project. I have a resolution of 5906 × 4169 px and three rectangles on which I’m applying Blur TOP with Filter Size 100, Filter Scale x 7 y 7, and Sample Step to x 2 y 2 (or other configurations of these parameters, which I need to increase), I get a Vulkan Device Error and TouchDesigner crashes.

I updated my Mac OS to Tahoe 26.5. I have a MacBook Pro M1 Max with 1 TB of memory and 64 GB of storage.

How can I combat this? What else can I do? I ultimately need to work at an even higher resolution, so this situation is very concerning.

Hey,

Does this issue only occurs with a large filter? If you are using something like a filter size of 50 is there no problem?

Affirm, the problem only occurs when I want to increase any of the above-mentioned parameters – for example, Filter Size 150, Filter Scale x 7 y 7, but also Filter Size 100, Filter Scale x 10 y 10, etc.

So the issue is likely that the operation is taking too long for the GPU to complete in the gpu-timeout limit of the OS. Unfortunately I don’t know of a way to increase this on macOS the way you can on Windows. If you need to do such a high filter blur on such a massive texture, you’ll likely need a more powerful GPU. Another alternative is to split up the image into smaller chunks, although with a blur that will likely result in seams.
