Performance drop in Layout

Howdy!
When I am in the Layout nod and move a vertex of a shape, I experiences performance drop.
Using WM 3.0 riverpreview2 Pro 64bit

It is smooth as silk in WM 2.3.6.3 pro 64bit

Is there any thing I can do to get back the performance?
Regards

I got a video that shows the difference 16Mb.

Cheers

It seems to me that the Riverversion updates the vertex in real time.
In older version the vertex updates when you release the mouse button.

Hi!
I really need this issue to be fix… Any news about it?

Cheers

Anyone else that have this issue?

I notice that the sluggishness disappears completely when I in the Layout select tab Overview and then press select, and then select tab Layout Generator.
I can now move the vertex without delays.
Otherwise it drains all my 8 core CPU when I try and move a vertex.

Cheers

I solved the problem by load older version, but I lost some project, due to new fileformat.

This performance drop is quite insane, especially in dev3.

I can see WM’s CPU usage fluctuating from 0.4 to 85% when I’m simply adjusting values (or trying to, actually) in the river reach node.

Is there a fix for this already, hopefully?
