Parallels 20 - Solidworks unusable due to graphics performance

Parallels Desktop 20.2.0
VM Windows 11 Pro (multiple versions tested)
Apple M1 Max, OS Sonoma.

After upgrading to Parallels Desktop 20, Solidworks graphics performance in "Shaded with Edges" mode takes a massive hit, becoming essentially unusable.

Models/assemblies rotate and zoom fine in "Shaded" mode (no edges). Switching on Shaded with Edges, incurs a long delay before the model reacts to a zoom/rotate/pan action and the reaction is then extremely slow/laggy. With an assembly of multiple parts Solidworks becomes unusable.

Section views in Shaded with Edges mode are also defective, with the section showing a mixture of Shaded with Edges in the visible sectioned part, while the model area that should be invisible during sectioning is instead overlaid with "Hidden Lines Visible" linework.

Tested with Realview implemented, without, and with software OpenGL. The problem exists in all cases.

At the moment I have no choice but to downgrade to Parallels 19 which still works fine graphically. (Both issues are solved when reverting to Parallels 19.)

Hope this is an easy fix to implement in Parallels 20.. Thanks.

 

Hi, tech report ID 485108976, video of issue uploaded. Thanks.

 

Any news on this?
I have the same issue on Parallels26.
When the shaded with edges is enabled, the performance dips immensely.
