I've used BIAB live for instrumental restaurant and private cocktail gigs for years and through these years I've been through at least four business-grade laptops, the last two being Levono. I get about as much RAM as they will hold and I have never had a problem. I run the Audiophile version and upgrade every year (except 2025, at least so far). I run BIAB itself from the laptop's disk and keep the RealTracks/Drums on the PG-provided USB disk, simply velcro'd to the laptop. I doubt I'll need that USB disk with BIAB 2025. I install all BIAB patches as soon as they come out and under the last couple of versions of Windows, BIAB has been rock-solid. Doing a "build" on a song just takes a few seconds. I've done this mostly as solo and duo but occasionally as trio and the guys I play with are UNT pro's. It really can be just that easy.
