Able to disable antialiasing, and lower any other visual features

[Anton Krug]

I do fairly large designs with many steps automated with TCL scripts, problem is then that when I try to interact with the design it's fairly slow. Yes of course that makes sense, but I'm getting sense that the visuals could be lower quality and could improve the rendering speeds. Maybe the intergrated graphics card on my i7 debian laptop doesn't handle antialiased lines well. I know integrated cards are not bests, but can play rage 720p at 30-45fps on the integrated card, yet I need to wait few seconds for a design to refresh, maybe the line drawing is not as optimised.

Hi Anton,

The current architecture has a performance that scales inversely proportional to the design complexity. So the slowdown you are experiencing is completely normal.

I am not so confident that disabling anti-aliasing will improve performance much, but I have not tried.

You can try using the "VisPyCanvas" branch (https://bitbucket.org/jpcgt/flatcam/branch/VisPyCanvas), that uses an OpenGL backend, which is significantly superior than the master branch that you are probably using. Unfortunately, that branch is not maintained and it might be somewhat behind in term of bug fixes and features.
