So after using this today, I get the same lag with notifications shade, recents, and lockscreen. Google now still crashing with ok Google commands using latest open gapps nano. Google now does the voice commands just fine, I wouldn't know if I didn't get the little sorry Google now crashed message.
Same story I had with AOKP pretty much.
Overall I love both the ROMs, I'm looking forward to improvements with the lag stuff. Being nightlies I hope that comes around.
