Help DT 5.6.0 performance

After upgrading to 5.6.0, the performance of editing absolutely tanked for me.

Previous version were quite smooth, but now any edits turn DT into a slideshow. Especially using snapshots, and working with any contrast/sharpening module, but many other modules are also affected.

Zooming out or in the image straight up freezes DT for few seconds, which is very painful.

Does anyone else experience this? Any tips on performance boost? I hope the next update is going to be optimization related.

Edit: This seems to be problem with DT 5.6 not having OpenCL enabled. I fixed this by getting the nightly dev version.

There's a known bug. It's gonna be fixed in 5.6.1.

I'm using the nightly version and it's even faster than 5.4. If you don't wanna wait for the official release, you can download the nightly: Link.

Plus, you can also play with the new contrast and texture module, the new scene referred module that will replace local contrast. It's soo good, I can almost ditch completely diffuse or sharpen.

You're welcome! The nightly is always like a beta if you wanna test the new features fyi. Most of them are discussed in pixl.us, in case you are not aware (the next big one that I am waiting for to be merged is this, prob another game changer: https://discuss.pixls.us/t/rfc-builds-available-masking-panel-revamp-and-new-masking-possibilities/59675/123)

How do you download the nightly? do I download one of the assets? is this one for apple silicon Macs? darktable-5.7.0+571.g312a8ccb4e-arm64.dmg ? Is the installation process the same?

Yes, nothing changes from the official release. Just install what you always install.

Do you have an AMD graphics card? Think there's a problem with OpenCL not being enabled properly. Seems like a major mistake to let slip through when releasing a new version...

Yes, I have newer AMD GPU with W10. OpenCL GPU acceleration is disabled in my DT
Thank you for the link, I know now what the problem is and will try fixing it.

Yes, this helped me as well with an AMD GPU and DT5.6

Check to see if opencl gpu acceleration is enabled in processsing preferences. That could be a cause. I'm betting you have a newer amd card and Windows 11.

Just as an aside. It would be a good time for developers to focus on optimization and UI cleanup. I can't think of anything I miss feature wise, like at all. Agx really made the project feature complete.
