I have a project file running on a laptop with rtx2060, and exactly the same project on a desktop with a 1080ti. the laptop seems to be consuming way more memory. The laptop is runming TD 2021.11180 and the desktop is on 2020.20020. if I open it on 2020.28110 on the laptop, the memory usage becomes about the same as on the desktop so I believe it might be a bug in the new version.
Files are too large to attach so I uploaded them to google drive:
Zip with assets and scenes included: Project Ring Memproblem.zip - Google Drive
Seperate toe file: Ring Projection Render V21.toe - Google Drive
