Skeletal mesh jittering in packaged game UE 5.2

Hi folks

I am having a major issue with my packaged game. During gameplay my characters hand meshes which are attached to the main skeletal mesh using set leader pose component in the construction script keep jittering. This does not happen in editor and did not happen in the previous version of the game authored in 5.1. I have tried playing with the physics assets of the hands, bounds scale etc and nothing seems to work. It also seems to happen no matter how far the character is from the world origin so I’m guessing that’s not an issue either.
I have also updated graphics drivers, tried different lighting methods, nanite and virtual shadow maps on and off etc and nothing seems to work.
I would appreciate any help I can get at this point as the rest of the game is working great and this one issue is stopping me from releasing the update.
Edit… This only happens when the character is moving
Another Edit… It seems get worse as soon as enemies are spawned in to a level. Don’t think its frame rate related as frame rate is still high and have tried with various locked frame rates.

Sadly replying to myself here!

Anyway managed to get it sorted by using ‘copy pose from mesh’ instead of ‘set leader pose component’ . It’s more performance intensive but gets rid of the jittering. If anyone has the same problem the details of how to do it are here Working with Modular Characters in Unreal Engine | Unreal Engine 5.2 Documentation
