Does 4.26 Movie Render Que use more Vram?

I am finding that 4.26 Movie Render que uses significantly more Vram on identical scenes, to the point where it is preventing me from adopting the new version despite the new features I want to use.

This appears to be true for Datasmith imports done with 4.26 and also for converted projects from 4.25.3

Are other people having this issue as well? I cant find anything online about it.
Scenes that use around 3gb of Vram in editor are exceeding my 3080’s 10gb when rendering, which drastically slows down the rendering compared with 4.25.3.

I am seeing a 20% - 50% increase in Vram usage between versions.

Has anyone else either experienced this, or not experienced this difference in performance?
Thanks,
Mike
