i have 32GB ram, default provision was 6gb, i changed it to 12gb and it's still laggy. It seems like it has ssd access lag, or graphics lag, i'm not a dev so I dunno for sure.
Bluestacks has always been highly recommended but I previously used NOX Player when I was really into an MMO game a few years back. That might be an alternative to check if you run into issues with Bluestacks.
I myself haven't tried an android emulator for quite some time, but you can try MEmu as it runs pretty smoothly and it's (probably) the least bloated Android emulator for gaming (if that's what you're looking for) additionallly you can also check this list and see which one suits your needs.
