Hi, thanks for the report. After testing I don't see any difference in 3.0.0 and other versions
Can you check with factory settings?: File → Defaults → Load Factory Settings

I did a test with factory settings and works better, not as quick as in 2.79 but def. better.
What I don't understand is why in a simple scene with not too much stuff on it happens that delay.
Gonna upload the blend for you to test.

With a friend, we saw that this issue happens when Material Preview is showed:

  • With Mat Prev open:

Hi, same issue is already reported: T94648: Timeline scrubbing is laggy when Preview tab is open in Material Properties
2.93.7 version works without any lag so I suspect it as regression (Will check later).

I did a test with factory settings and works better, not as quick as in 2.79 but def. better.

The original issue reported here appear to fixed with factory settings. So I think we close this report.
Also- While we do continue to work on improving performance in general, potential performance improvements are not handled as bug reports.
To improve performance, consider using less complex geometry, simpler shaders and smaller textures.

Feel free to comment or reopen the report if there is any misunderstanding.

Buenas,

The original issue wasn't fixed by loading factory settings, only make it better cause Material Preview wasn't showing.
The testing file before factory settings was a cube and a plane with simple materials.
It is not an improvement request, but a bug, since it is related to a previous version funcion that was working well, the material preview, and now isn't.
Now when the Mat Preview is showed, there's an issue with performance that one can see it easy by dragging the Playhead.

In video of your original report,was material preview open?
If yes, it's indeed a same problem- T94648: Timeline scrubbing is laggy when Preview tab is open in Material Properties
I am considering your original report description and the comment T95748#1308429 both as separate issues. Are they related?
