2022 Sky replacement very slow on Windows 10.

Hi Keith,

Thanks for reaching out. We are here to help. If you can clarify a few things for me, we can get to the bottom of this.

Could you please share more details from the Help > System Info in Photoshop? Does this happen with all the documents in Photoshop? Are you working on Raw images or Jpeg images? Are you applying the sky replacement at the beginning of the editing session or during normal usage? Have you tried any troubleshooting steps?

Similarly, please go to Photoshop Edit > Preferences > Performance > Use Graphics Processor > Uncheck it and restart Photoshop. You can also optimize Camera Raw, which handles Raw images in Photoshop, by going to Photoshop > Preferences > Camera Raw > Performance > Uncheck Graphics processor and increasing the cache sizes.

Please check this series of suggestions related to software optimization and in-app changes you can do to optimize Photoshop's performance in this article, and please give this a detailed read through: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

Let us know if this helps. We hope to hear from you soon. 

Thanks!
