I set my external monitor as my main display and use the hybrid graphics option. I will get lag spikes when using firefox, transitioning between programs, etc. I looked at this link and saw that it's an issue with using hybrid graphics. Is there any way to fix the lag when using hybrid graphics?

When your external monitor is displaying, try killing dwm.exe.

I've tried that a couple times before but I still get lag spikes afterwards. Thanks for the help though. I might just run it in discrete mode whenever I plug in a monitor for now unless a more permanent solution comes up

Yup, this issue is caused by Optimus and the exact cause is unknown: could be Windows, Intel or NVIDIA drivers.
I vaguely remember someone mentioning that the issue went away after disabling Windows fast boot or something similar (eg having Windows do a full slow boot). Might be worth trying.
