Some machines sputter and stutter under the load of the new option.

There is thus an alternative to NOT use it.

There is another thread around here about a 'test' you can run (3rd party) to evaluate your system.

I'd be cautious if my machine was running xp, had only 1 gig of memory or less, and is of the Pentium type. However some of the caveat is dependent on how much background stuff is running, and what you are loading at boot up. Some people have a bunch of apps, say 3 cameras that are being looked for, printer managers, both wired and wireless internet, virus scanners, and other software that is loading you might not be aware of.

The cautious approach is to not delete files, try the new engine, and if it causes problems to leave things as they are.

On the flip side the RealTracks sound better, and in my case I went from having a full 500 meg hard drive (and one empty one) to having a 60 percent full primary drive due to reclaimed space when I erased un-needed files. As I had all the RealTracks/Drums that meant a substantial saving, your mileage may vary.
