Yeah it's true.It may be different for another computer but since I reverted back to v1.6 my CPU usage is under control.So methinks that the Gamebox exe is crap.
I'm running 1.51 - so can't speak for later versions at all.
Stopping processes is a different matter, but that's also something you can do more safely yourself. Not safe as in "Oh my this program will steal your viruses and infect your bank details", safe as in you can shut them down properly and not just kill the processes.
I've never needed to clean boot, the trick is to not have a million and one software daemons running from things you've installed that think they're important enough to justify an always-on element, and actually closing down applications. Everything else is snake oil. You can't "clean RAM", because reading and writing to RAM is almost a free action it's so fast relative to everything else, you can't intensify processor performance because most of the time you can't change that through software, and if you can you damn well shouldn't do it automatically.
Obviously you're free to use a third party application half-based on proven useless techniques if you wish, though.
I'm fully aware of "snake oil" tactics - in fact it's used by like everybody in the world since the stone age so not particular for Gamebooster. Basically, you have to be a critical consumer, esp. when it comes to free stuff as they tend to want to lure you away to paid versions etc. It has been the same since forever for almost all freeware so again not particular for Gamebooster. It works perfectly fine for what I want it to do, i.e. keep track on unnecessary processes, shutting them down if I want and restarting them if I want. Haven't noticed anything "unsafe" at all with it really. Basically, I think you guys have a point but are over-reacting. Gamebooster doesn't even register on my OMG! radar. :shrug:
Here's one example of the importance of shutting down processes, regardless of which method you're using: http://www.gamesas.com/index.php?/topic/1165908-oblivion-wont-start-even-with-mods-disabled/.
