Addon vs Custom build render speed

[BurkulesLDN]

Hi there!

I am still using the old custom build but like to dip my toe into the addon version every now and then to see how it is coming along. So today downloaded the latest stable version (31.10).

And I can't help but notice the difference in render speeds is still pretty large:

In the few different test renders I did across a few old projects of varying size and complexity, I was getting render times that 30-50% slower in the addon version. In the custom build I can get 24fps viewport playback on a simple scene, in the addon version (with the exact same file) it is hovering around 7 fps.

Has anyone else noticed the same?

Team Octane - Is this a known thing or am I an outlier here? Is there a plan to match addon performance to custom build? Or is the addon version inherently just going to be slower due to the new software architecture?

There are so many great features in the newer versions I would love to use - but as I do a lot of animation work, 30-50% longer render times is sadly not something I can build into my timelines.

I really appreciate all the amazing work of the developers and whole Octane team in bringing us Octane Blender, which has been a massive game changer for me and I'm sure many others - but I guess I am just really curious to know if the addon version with all the tasty new features will be usable for people like me, or if I will be stuck forevermore on the (perfectly working and solid) final custom build?

Apologies if I'm bringing up something that has been discussed plenty before at some point, but I couldn't see another topic that seemed to address it!


Cheers,

Adam.

Hi Adam,

In terms of render speed and overall performance, the Custom Build and the Addon version should be very close.

The differences you are seeing seem larger than expected, so it would be very helpful if you could share one or more scenes where the performance difference is clearly reproducible. That would allow us to test them directly and better understand what is causing the slowdown.

Thanks!

Hi Lino,

Thanks so much for getting back to me - and that is very exciting news that I'm the outlier!

in the depths of animation deadlines atm but will prep a file for testing your end once i've got my head above water!

Cheers

Adam.

Of course, no worries at all, Adam. Animation deadlines come first.

Whenever you have a chance to prepare a test file, it will be very useful for us to investigate the performance difference properly.

Thanks again!
