KDE 4.11 Beta 2 Is Now Available For Testing
Phoronix: KDE 4.11 Beta 2 Is Now Available For Testing
The second beta of the KDE 4.11 Software Compilation has been released...
When I tried 4.11 beta I was amazed at how much faster/smoother kwin is. Its a night/day difference from 4.10 on intel, and finally no tearing! will be a great release. The new QML task bar also seemed a lot less buggy than the current one.
On Intel Ivy Bridge (ULV Core i5, HD4000), Kwin is butter smooth. You ought to say what hardware you're running to have dog slow performance in 4.10. It must be so old, rotten, crusty and dusty that probably not many are in the same boat as you, I'm afraid.

I'm afraid you and I just have very different standards on how smooth and well performing compositing should be. For me in 4.10 and previous, kwin was simply not there IMO, but in 4.11 it is, and its smoother than unity or gnome-shell now

Also things like hovering over the taskbar for live previews had noticeable delays and lack of smoothness. When I tried 4.11 all this was improved across the board. 4.10 was usable, but I wouldn't have called it smooth on HD4000. (and before you blame the distro or something, I've tried kde 4.10 on various distros, kubuntu, opensuse, mageia, chakra, arch etc...)
Anyway, regardless of performance, I don't know how anyone could stand using kwin on intel graphics prior to 4.11! watching fullscreen videos, there was always noticeable tearing on the top inch or so even with kwin's vsync enabled. The only way I found to work around it was to set kwin to totally disable compositing when mplayer was open and use gl output for mplayer, unfortunately this was far from ideal because for some reason with mplayer's gl output I got tearing on certain videos still (yet others were totally tear-free, it was very strange). I tried VLC but vlc's gl output is even more broken and is simply incapable of preventing tearing on intel because it doesn't pageflip. Tear-free video is an absolute must for me, and any compositor that cannot provide that I deem "unusable". I'm very happy kwin can finally provide this, and along with that now also provides some of the best compositing performance I've seen, the developers did a great job in this release.
