[Spice-devel] Fedora 18 guest's GUI is slow. Due to 3D driver?

It didn't even work until recently (with the release of Fedora 17) as seen in this features page for Fedora 17:

https://fedoraproject.org/wiki/Features/Gnome_shell_software_rendering

As you probably know, GNOME 3 has the 3D required desktop and the Fallback mode desktop.  I believe the Fallback mode is supposed to be discontinued if it hasn't been already... but if it is there, you can use that and it should be much faster.

Other than that... NO there isn't anything you can do to fix it.  You'd have the same problem pretty much with any composited desktop that wants hardware accelerated 3D.  As someone already said, Windows works ok because it disables the Aero interface.

KDE's 3D stuff seems to work fairly well in SPICE but KDE has two modes and doesn't require hardware accelerated 3D for one of them... which is the one that works.

So, if putting a fork in your eye hurts, don't put a fork in your eye.

You could run your GNOME 3 desktop on a really fast VM host and have a really fast client connect to it... with a really fast connection (1Gbit) and it'd probably work a little better... but until SPICE ads support for hardware 3D acceleration... or the GNOME 3 guys change it, you get what you get.  In fact, there are a bunch physical machines withof video cards that don't work well on Linux that GNOME 3 either won't run on at all... or runs poorly.

TYL,
