XBench is an old benchmarking tool and can be very inaccurate at times. I would not rely on it if I am deciding if my system is running well or not.

I'll be glad to know if anyone can figure out what this update fixes and what was causing the problems to begin with.

Wow! This update doubled the speed of my computer!

Oh wait, no it didn't.

Nothing at all has changed as usual.
