V22 - very slow refresh rate in sketching mode

Is anybody have same issue?

3D mode is working fast but when I want to create a sketch the refresh rate is very slow. Is there any setting what I need to switch on or off?

I think this is not hardware problem.

Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz
Memory: 8192 MB

NVIDIA GeForce MX130
1920 x 1080
Memory: 4166 MB

 

Not necessary a complex thing a simple line drawing is slow too.

 

I've been having the same issue with sketch mode.

Any ideas on how to speed things up?

 

I have seen an issue with my 3dconnexion Space Navigator (now obsoleted and replaced by SpaceMouse) that occasionally, while in a sketch, becomes very, very slow and jumpy while attempting to move or rotate the view. And I don't have complex sketches. This may happen whether editing a single part or if editing a part from an assembly in a new window. The only solution I've found so far is to shut down and restart Alibre, but that sometimes won't resolve the issue. Eventually it returns to normal.

I have also noticed a marked difference if I have Ambient Occlusion turned on or off. With AO on sketching is definitely slower so I opted to turn it off.

 

Thanks for the tip HaroldL. I'll check AO next time I see this happen.
