I don't know why I am still working with vista.
Maybe its new promising memory management. It was supposed to be great.
The bottom line: it is very slow. very.
Even after turning off all the things that might be the blame for being so slow: anti - virus, firewall, defender...and of course UAC. It is still much slower than the machine I have at work (which is at least two years older than the one i have at home).
Maybe it is DX10. I haven't tried it yet, but with the overall performance of the system, I don't expect much.
Needless to say all the fancy graphics is the first thing i turn off after installing windows: I am setting it to the classic scheme. Funny, I never had to turn off graphic options on KDE.
