Default Re: 8400M GS : Low performences

Nope, installed nvidia binary driver because this

In terms of speed I'm merely referring to Qt painting performance, overall kde4 is much faster esp. startup times.
I was talking about painting performance as well,
startup times are usually rather bad on live systems.
However, I did not try out each and every effect out there,
so it is rather basic performance
(drawing windows and contents)

As for glyph cache: jup, might be that this setting
is useless by now. I tried it with InitialPixmapPlacement=2,
but this is really slow on some operations on this (notebook, turbocache) GPU,
so I switched to InitialPixmapPlacement=1 which gave me some
performance boosts in compiz, e.g. window title update (emeral) on window maximize.

Edit:
(If you have more to say: don't use edit please, I wont reread this thread
much if there is nothing new going on, so I don't see your new request)

XRender benchmark, aborted after a while
(for full results: maybe tomorrow, until then I need to
work on this notebook and can't do longer tests)

Code:
fuchs@thinkfox xrenderbenchmark $ ./xrenderbenchmark
X Server from: The X.Org Foundation, Release: 10300000
        Xrender version: 0.10
