Sounds good to me! I'll wait for Qt5 then before giving it Qt another
serious performance test.

Almost all less than 5 years old PC hardware has
either a nVidia, ATI or
Intel GPU, that is not necessarily powerful but definitely has enough
power to render standard controls with OpenGL.
I was testing Qt4 on an Intel graphics system and it still seemed
sluggish. :-) Another area of concern is with remote desktops (e.g. thin
clients); how will rendering be handled in that case? Will we need to
have Chromium (the GL renderer and stream processor, not the browser)
developed and installed to make things work?

practically, even slightly sluggish performance is quite
noticeable to power users. Many applications, upon converting from
Qt3 to Qt4, appeared to slow down noticeably.
Even with a common Qt-internal style
such as CDE or Win9x ?
These are just my $0.02 and experiences in working with Qt 4.7. I am
open to looking at Qt4 again once Trolltech fixes the raster graphics
problem for good.
It will be "fixed" with Qt5, which will have OpenGL ES
2.0 as the only
graphics system. It had better work well with llvmpipe...
