IMGUI performace and related issues

[TylerTemp]

IMGUI has some performance issues in SaintsEditor. Some attributes like ListDrawerSettings is nearer unuseable for IMGUI. I haven't dig into it yet (but I guess it's because the changes in SaintsEditor for IMGUI...)

At the moment I need to set IMGUI related issue to low priority.

One is because it's already lack of support from Unity as Unity has been moved to UI Toolkit.
Two is there are already much hacking around for IMGUI, patching too much is not affordable for my spare time and energy...

I'll back to it later, but just not the recent time.

Leave a thumb up if you don't work with IMGUI (means you're using UI Toolkit), thumb down if you're a IMGUI daily users. If there are many IMGUI users then I might to make it a bit higher priority.

Update:

Actually, after some digging, the most part of the performance issue came from auto getter's loop. This impact both IMGUI & UI Toolkit, but IMGUI is worse than UTK.

Please go window-Saints-Create or Edit SaintsField Config, and disable the loop interval under Auto Getters Configs setction.

IT'S RECOMMENDED TO DISABLE IT IN EITHER CASE. I don't change it to the default behavior, because for UTK there are some method to get rid of this static update and gain much better performance, which will be added in some recent updates.

(Which means, IMGUI related issue is still a bit lower priority on UI Toolkit, but I'm now back on it)

And, thanks for your support!
