kwin performance

my only real gripe with kde4 is kwin performance. is nowhere near as smooth as compiz fusion and others.
and that's a i7 with a rather fast intel graphics (yeah yeah its not an heavy 3D game but hell, its WAY more than kwin should need - and certainly compiz/win7 and even osx run extremely smooth)

It runs great with my mediocre laptop, but only if I use proprietary drivers. Then again, same holds true for Compiz.

I know that's not very hopeful.

For my Radeon based setups, the open source driver runs much, much better on Compiz than kwin. I defiantly think there is a lot of room for performance improvements in kwin. The ATI drivers are much faster, but tend to be less stable. Kwin's feature set is useful enough that I tolerate the less than flawless performance.

From the link:


KWin, Plasma's window manager now supports OpenGL-ES 2.0, improving performance and deployability on mobile devices


That may also help on desktop devices as well.

Also interesting from the link (http://www.kdenews.org/2011/02/18/kwin-embraces-new-platforms-openg...) describing those changes..

The work on OpenGL ES not only brings improvements for the use of KDE Plasma on mobile devices, but also significant performance improvements to all users of the Plasma Workspaces. The code written for the mobile platform is reused in KWin for the Plasma Desktop and Plasma Netbook Workspaces.


It goes on to describe how this is a necessary step to moving to wayland in the future! There is also a video of it running on a n900 and an unspecified intel tablet.

At various stages in the KDE 4 evolution kwin did indeed have poor performance at some releases. Sometimes this was due to kwin itself, and at other times it has been due to kwin exposing deficiencies in underlying drivers that have been dormant for years (with no programs actually exercising the drivers in that way).

Lately though, it has picked up again. On my modest Athlon 64x2 system, kwin with compositing (Arch Linux, KDE 4.6.3) is faster and more responsive than Windows. Some time ago I used to have to temporarily switch off kwin compositing (Shift + Alt + F12) if I wanted to view anything but the smallest of videos smoothly, but lately that has not been necessary.

It runs *perfectly* on my 5 year old laptop with a crappy Intel 945GM (added an extra gig of ram and changed hard drive though)

IMHO if a DE runs this smooth in 5year old hardware it means it's doing great!

If it's not smooth in an i7 there must be a problem somewhere else, I doubt it's kwin's fault.
