There's no more steps to Vishnu then to Fps Pack. The same. You still have to load from the installer once...then from the game once. Same thing with Vishnu, you load from Vishnu once then from the game for a cold start. The only extra step possible is "Load Slots" which Pack don't do because...Well, you can't save with it....The crap you heard from Ben was just that.....crap. The 5 steps total you read on the site includes packing the game originally.. >.< t
And Vishnu isn't "meant" to be more secure, it "is" more secure....FPS Pack provides 0% protection. It's just a packing utility, nothing more at this time.
And no Non FPSC specific application works because of that simple reason. There not FPSC specific. You'd have to code your own if you liked niether of the choices available.
