There's a loss of power of the TOPs in the latest version

Bugs

I noticed that in the case of feedback in TOPs with pixel addition and variable resolution (the texture grows with each frame) the fps really drains before the resolution reaches a considerable size. In fact if I include a little math and texture operations like displace or crop in the feedback, the fps drops to 3 in an instant. The same network in the old version 2023.12000 runs smooth like butter with 60 fps and huge textures.

I’m using this method for recursive division and I realized that my only option left is to start from scratch with a maximum size texture and transparent pixels. I imagine I understand why it’s cleaner and more efficient with a fixed resolution texture in a feedback, but that means 2023.12000 is so powerful that it doesn’t really care about resolution variation.

Has anyone experienced any other minor ‘weaknesses’ of TOPs operators lately?

Thank you massive, I love you guys.

Hi @paketa12

for us to quickly analyze this behavior, could you share a example network as a tox with us?

cheers

Yes, sure.

Here are two files. The pixel addition is a much simpler FDBK, and the other has that splitting thing that I covered in a tutorial a few months ago. The first one gets to 24fps very quickly, sometimes a little later, but always drops. The more complex one drops to 4fps very fast. The '23 version I mentioned above runs both of them smoothly up to a length of 32768px.

thank you massive, Markus.

Hi @paketa12

this is a bug that has been addressed and a fix will be coming with the next release of 2025.30k. (2025.32959+)
