I'm not OP, but I last used it a couple of years ago and it was pretty slow (I was using an i5-2500).
Has it improved markedly recently, and if so, how?
It now uses Intel's HAXM on Windows to increase performance tremendously. It also allows for the saving of snapshots to launch the emulator almost instantly.
Android emulator on my Macbook eats 100% i5-7560 CPU, drain battery in a hour and scroll with touchpad does not work
