The controls weren't too difficult for
Pro Beach Volleyball. Basically, X does everything, and if you want to add some power, hold down square. Once you get a little practice, work on directing your shots, so you're king or queen of the court. However, loading time is a little bit of a hassle to deal with, because it takes some time. Thankfully, it only takes one memory block to save a tournament and created player.
PS2: After switching the settings to Fast speed and Smooth graphics on my PS2, I really didn't find much of a difference. The loading time was a slight bit faster, but nothing very noticeable. The graphics didn't change at all in my opinion, so there really isn't a need to try and change the settings.
Since Super Spike V-Ball for old-school Nintendo, I haven't played any good Volleyball games. Well, Power Spike Pro Beach Volleyball isn't anything great, but it will find some room in your playing time.
