Storm 3 is a mess, on my computer at least. It is pitifully slow at screen redraws and responding to mouse-driven commands, like calling up menus. It takes a miracle to get the Storm window to come all the way back after the screensaver kicks in. Storm 3, unfortunately, is unusable on my PC.
I suspect all this has something to do with the fact that Storm uses Java as its motor. In my experience, everything I’ve seen that uses Java is problematic. The more complex the program, the more likely it is that Java will fail to keep up.
Installing Storm 3 also installs j2re1.5.0, “Java Runtime Version 1.5.0.” I wasn’t asked for permission, it just happened. Oddly enough, at the Java website, the most recent version available is 1.4.2. Is Arturia force-feeding us a beta version of Java Runtime?
As a caveat, I don’t know squat about programming, with or without Java. But I do know that Java and I have never gotten along, and that I’ve read no end of similar complaints in articles and forums, so I’m not a lone voice here. Start over. Dump the Java.
