“If you can use 45 degree traces, you can use 90 degree ones with no measurable impact. Use which over one you like or is suited for a specific trace density. Engineers never used to care, and there is no reason you should. Don’t let the unsupported answers (upvoted as they unfortunately are, despite being false information) pull you in. Validate rule of thumbs you’re told with data. Tradition and faith has no place in good engineering. “
This is excellent advice for things other than PCB traces
