KDE "Stephan Binner, a well-known KDE and openSUSE developer, has released a set of live CDs featuring the latest development snapshot of KDE 4 (screenshots). Unlike the SLAX-based live CD called KLAX, which he used to develop in order to demonstrate new KDE releases, his 'KDE Four Live' images are based on openSUSE. After a large, uncompressed live DVD released earlier in the week, a set of smaller live CDs (compressed with Squashfs) is now also available for download. Don't expect trouble-free computing with these early KDE 4 snapshots, but as demonstration tools designed to give KDE users an early taste of things to come, they aren't too bad. The first alpha build of KDE 4 is scheduled for release early next week."

On linux, if you don't have accelerated Xrender, Qt4 is indeed a bit slower than Qt3. But with hardware accelerated (even with a low end graphics card) it's much faster.

Like I said, I used Qt 4 on Microsoft Windows, too, and it is slow and CPU hungry there, too.

Which version of QT 4 did you use? It was my understanding that early versions were quite a bit slower than the newer ones. I also think that certain types of code require a rewrite rather than just a port from QT 3 in order to be fast. Were you making QT 4 apps from scratch or porting something?

Nobody has accelerated Xrender. Only r200 of all the cards have accelerated Xrender. For every one else, are we just screwed?

The latest NVIDIA drivers have XRender enabled by default.

In XGL XRender is accelerated through glitz (Cairo backend). AFAIR, it was, along accelerated compositing, other big feature of XGL. Also experimental Glucose patch(es) should allow for this with AIGLX.
