Yes, I definitely enabled all the beta/testing features. Tabs may have been limited "depending on screen resolution", but as a gamer I had probably one of the biggest screen resolutions you could run, with a CRT to match. I'm pretty sure I was using an AMD K6-2 500Mhz with between 128 and 256MB RAM. Sometime after 2002 I built an Athlon-based system with a gig of RAM, so I could be mis-remembering my computing platform when "peak browsing performance" happened, but I know that no browser has ever been as fast as Phoenix was.
