AMD R600/700 2D Performance: Open vs. Closed Drivers

[Dr_ST]

Michael, have you checked performances using compositing effects (normal and high), i've seen great improvements in catalyst-powered graphics when the composition is on. No idea why but i think this is worth the test... (and yes i mean in 2D rendering...)

What is the oss's performance vs windows's 2d performance? I am not talking about benchmarks performance, but pure experience.

Windows GUI *seems* to be more responsive.

What if composite is turned off?

That's not really relevant in this... Windows with or Without seems more responsive than Linux with or without compositing.

So what are the concerns about vista then?

Perfomances are not good, and the interface is a bit confusing.
I used it just for a couple of hours, but I found myself lost in the menus. XP was somehow more simpler and straitforward.

I for one would not be happy if my work consisted solely of cleaning up other people's buggy code.

Have them swap sides every month. Or better, have a regular competition to find more bugs in the other group's code than they can in yours.

Hey, it works for NASA.

So when, if ever, will linux have as good 2d acceleration as windows?

Is it because of EXA, kde/gnome, Xorg or another peace of the gui system?

Compositing on Windows was since Vista. Back when it was still called Longhorn, and when GPGPU computing was non-existant, the idea was that if the UI was to run on the GPU then Windows would become faster (Vista was to be the Mac OS X experience on future Windows PC's). Then there came 3D desktops and Vista needed to have that feature too.

So now you have shitty performance with the 2D desktop (burden on the CPU) and the only way to activate GPU accelerated desktop was by enabling compositing which was also putting more burden on system performance.

The workaround? Demand more CPU and GPU time. So on computers that run terribly slow with Vista you still get an insanely respnsive GUI with terrible compute performance.

So there is no way to compare Windows performance with Linux but to test it on Windows XP...

Eh, isn't that mostly optimizing for desktop performance at the cost of other stuff?
