That looks like your hardware isn't configured correctly or just broken.I have tried Sabayon, Mint, Ubuntu, Xubuntu, Fedora, Crunchbang and none gave a smooth desktop experience on that machine for kids. Regards to the CPU usage, no matter what software being used (CMUS, Audacity, DeadBeef, GNOME player, VLC, etc). Note that this behavior happens on Windows XP and Windows Media Player too.
I was only that ballsy, it actually worked without torturing people. Am I a here now for knowing how to configure an OS for a low-spec system? Or is your argumentation just invalid?In conclusion, when installing modern software on ancient hardware and expecting them to run smoothly, you should be quite ballsy or willing to torture somebody.
Can anyone pls explain to me what kind of specific advantages it would bring supporting sse2 (or sse3) only cpus?
http://en.wikipedia.org/wiki/Streaming_SIMD_Extensions ... and http://en.wikipedia.org/wiki/SSE2 (the SSE2 article also has a paragraph on the differences between 'the slower x87 stack' and SSE2.
Oh and props to Qt for implementing charset conversions with SSE2, that's the first I hear them used for that. Even if it's been in Qt for three years now.
So what does this have to do with Qt 5? Well, they are using SSE2 (and higher versions if detected) on their 64bit releases, which accelerates their QML stuff. However on 32bit builds, all kind of SSE optimizations are turned off (By default). So this is going to be a pure win for modern CPU owners, who are running a 32bit OS.
Regards to the SSE3, it's going to give them ability to process 4 single precious floating point numbers (stored in one SIMD register) horizontally which wasn't possible (directly) in previous generations. This might be slower or faster depending on the hardware.
but even GLib these days have a codepath to use SSE2. No idea what the fuss, since don't remember people talking about it when glib introduced a similar approach.
If you have an old 2000-2003 computer you should either stop using new software and go back to Win 98/Linux 2.x based kernel distro, or get new hardware... plain and simple.
