[gentoo-user] Compiz effects vs kwin

[ubiquitous1980]

The effects in kwin (such as window wobble) are vastly less smooth than
that in compiz.  I have noticed that compiz is faster in both kde4 and
in gnome (with slight preference to gnome in speed) and wondering if
this is normal, or something to do with my kwin setup.  Running on GM 965

Thanks,

Damien

for a lot of kwin effects you can change some settings making them smoother. 
Also AFAIK in kde vsync is turned on.

kwin got crappy animation speed in KDE 4.4.  It was as smooth as compiz 
in 4.3.  I asked about it in the KDE mailing list, but there was zero 
interest in this regression.  So you either have to live with it, or 
switch to compiz.

Thanks for your reply.  I am currently using kde 4.3 because I try only
to update to downstream-stable.  Is there another explanation?

Thanks,

Too old drivers and X maybe.  Since you're using downstream-stable, but 
the cool DRM/GL/KMS stuff is only in the latest upstream versions, this 
might be the problem.

kwin is slower on intel cards. Kwin with gnome or xfce is much
faster... Intel video cards are very slow...

From my experience every version of kde above 3.0 is slower than any
other window manager (gnome (sawfish, metacity, enlightenment),
xfce(xfwm), compiz, lxde,...), on every machine I've had. It needs more
memory, faster hard disks, stable filesystem (ext4::delalloc?), better
video card... and so on. Even Qt seems to be slower than GTK+ if you
launch application that does similar thing.

...or it's just my imagination :)

If you want smooth kde get a nvidia or ati card, at least 256MB, 2GB
ram, 1.6GHz.

You could also try nice/renice

Thanks for your advice.  It seems that this is the way of things: compiz
is very efficient but slightly incompatible with kde 4.x and kwin is
highly compatible and integrated but uses a lot of horse power.

Thanks,
