I have created a 3d section (free section observed from an isometric view) of my not-so-complicated model. If I select to "consider transparency" in the section properties and the drawing file with the section viewport is active, the performance impact is huge. I guess the rendering time (refresh) of the working viewports is affected, noticable after every minor change/edit/use of tool in the project.
The video card is GTX 1080 (8GB) with "studio" drivers and I use the OpenGl API.
I would like your opinion on this issue:
- Is this behaviour expected for 3d sections due to the not so powerful GPU?
- Is it possible that the drivers are not installed correctly?
- Why transparency in particular generates such issue? (If it is turned off in the section properties then the issue goes away.)
