Are you talking about rubber-banding? In kde3 you can go to 'Control Centre' -> 'Desktop' -> 'Window Behaviour' and click on tab 'Moving'. There you can select if you want to display contents of moving and resizing windows. This is not a new trick. I get your point about kde4 being slow on machines that don't have fast GPU. But a fast GPU should not be a requirement, i.e. some people don't want all the eye candy, they would rather have a basic and fast desktop. Anything on top of that should be optional. I think kde4 is trying to be so much like Windows Vista or Mac OS X, they have neglegted the basic philosophy of Unix - keep it simple stupid. "
I didn't say it was a new trick ... I'm just pointing out that it is so. KDE3 used software rendering of the desktop, and KDE4 uses GPU hardware-accelerated rendering.
If you don't have a hardware-accelerated graphics capability (a working GPU) ... then KDE4 will be slow.
If, however, you do have a hardware-accelerated graphics capability ... then KDE4 is quite fast.
This is probably by far and away the primary reason why the user experience with KDE4 apparently varies so much from system to system.
On the system I am using right now, which has a fairly modest dual-core AMD64 CPU, 2GB RAM and an ATI Radeon HD 2400 PRO graphics card, as I type this, KDE4 is faster than any other desktop system. It absolutely flies. It is noticeably faster than XP and GNOME on this same hardware.
About the only thing that would be as fast is a very minimalist lightweight desktop such as JWM (Puppy Linux) or LXDE. But they are not much fun ...
However, I fully realise, YMMV. Not everyone has a system that runs well with KDE4.
