Hello,
I just autoupdated from version 3.4.? to 3.5.31, and it seems it has some performance degradation. Undo seems to take a lot longer now. It's about 2 seconds in my project, whereas I've never paid any attention to how long it takes before (which is isn't really proof it's slower...). My project is kind of large with about 17 skeletons (with 10-20 bones each and some meshes here and there), I guess I could split that up into multiple projects if that's an issue, but I'd rather not if this can be fixed? Its quite a pain currently as it makes it much less friendly to use as you never kind of know what's happening and if the keypress worked or not.
Is this something known or something that could be improved or will I just have to manage?
Some other things I think I noticed. Changing between Animate and Setup modes now takes longer (about 2-3 seconds, not sure how it was before, but it too 'feels' slower) and exporting an animation sequence to png files also takes longer. These don't matter that much, but thought I should mention if it gave any clues. But as I don't have the old version to compare with I cannot be 100% sure if I'm right also.
