Low FPS when "Move" or "Rotate" gizmos selected

Bug Reports Studio Bugs
#1

Reproduction Steps

1. Select “Move” or “Rotate” gizmo in Home or Model tab
2. Observe a consistent, noticeable drop in FPS when not actively dragging a handle & moving something

The microprofiler points to a lengthy GetSetting call. I’ve tried reinstalling Studio, disabling all beta features, and disabling all installed plugins, to no avail.

Can you show a video recreating? I’m using similar hardware and can’t get the same outcome.

I woke up today to a similar issue. I’m just spinning the camera slowly at a constant rate and it will randomly hiccup. This looks like a frame lag followed by a rotation jump over 90 degrees from the last frame. It’s occurring on all my local games. It’s super disruptive!

Edit: I restarted my machine (literally only had it running for an hour) and I’m not experience my low fps issue now. It was probably unrelated to the OP’s issue.

Hi, nomer! We’re going to investigate this soon, will report back if we find anything. Thanks!

Yikes, I know what this is.

If you briefly hold down Tab to summon the handles at least once with each dragger tool selected that should work around the issue for the time being until we can get a fix in.

(TL;DR: The result of GetSetting isn’t getting cached but once you use handle summoning it will start getting cached correctly)

Filed a fix for this internally. We’re on code freeze right now so won’t come out until beginning of next year. Thanks!

Looks like this was fixed late last year, and I cannot repoduce. Marking this bug as closed.

Oh no you don’t! I have this issue, however it occurs the other way around. When I try to drag a large object with the move tool, my frames will drop.


This was only SEVEN objects.
