Filter > 3D > Normal Map not showing adjustments in Real Time anymore...

I'm not sure what Ecosystem means, but I couldn't find a forum just for regular photoshop. I apologize if I'm in the wrong forum.

I'm currently using Photoshop version 23.2.1 on Windows 1o. 

Previously when using Filter > 3D > Normal Map you could see the adjustments you were making in real-time. Which is a necessity. 

Now this is not longer so. I cannot see the changes until I commit to clicking the Done button. Then if my changes are incorrect, I have to start over. This is not acceptable (in my opinion anyway).

I know this was an issue in the past, and could be fixed by choosing Preferences >Performances and check "Legacy Compositing". However, this option is not available in my current version of Photoshop.

Please can anyone tell me how to regain real-time view for changes. I really hoping Adobe doesn't find this acceptable to do away with.

I appreciate your help. Thank you.
