Slow performance in 2D sketch

[alis990]

After last update, I'm encountering low performance only when editing sketch in nested components.

Even when I create new project, then empty component, then nest inside another one in which i make sketch.

That was never an issue.

I'm still running Win7, so it can be partially that.

I changed graphics driver to OpenGL, and it helped, but it's not as smooth as before.

Is Fusion 360 supported on Win 7?

Can you Attach a *.f3d file here that exhibits this behavior?

Officially no.

As said earlier, even new projects have that issue.

I didn't see anything obviously wrong - in fact, it looked pretty good.

I suspect the issue is with the Win 7 OS or maybe graphics card/driver.

Graphic card driver is from 27 II, so newest. I updated it before posting.

I have same issue. When sketch shown i have a very low performance. When i hide all sketches all go work very fast. With many elements on sketch (10-20 primitives) it so slow so i cant set dimentions or move dots or lines. VERY slow.

Windows 8.1 i not change anything for a long time and have this low performance issue just after last Fusion 360 update.

This sounds like a completely different problem.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Okay. I also record video: https://www.youtube.com/watch?v=xeGc8eCMvtM

First thing I would do is simplify your sketches.

As part of that simplification - I would fully define the sketches.

On the left is your first sketch - on the right is my simplified sketch.

But this not answer why showing sketch make editing so slow. First sketch is not so much but second one i cant edit well while it so slow. When i try set dismention i need wait with mouse down button for a few mins! This is abnormal and not exists before.

I had some graphics performance problems after the last update and found I need to change the graphics driver to OpenGL.

Thank you! I test all 3 options and All DirectX work very slow with sketches but Open GL work very fast.
