I have been using Blender 2.92 for a few months (using the grease pencil) and it started lagging a lot on a specific file (0.92GB), particularly on specific scenes. It lags so much that I can’t sculpt, undo, select, switch modes etc. without waiting at least 30 seconds. I really can’t continue my project at all.
I have tried to open my file on a computer that has lots of RAM, but the problem persists.
I also tried un-checking Global Undo in my settings, reducing the lag a bit, but it still does not work well enough.
I saw on YouTube that in earlier versions of Blender, we could modify the Window Draw Method, but I can’t figure out where to find it in my preferences (and don’t know if this solution would work).
