LinuxQuestions.org - slow XGL effects

Hi everyone,

I have XGL working in Fedora Core 5 with an nvidia geforce 5200 card, but it's pretty choppy opening and closing windows and switching between desktops (by "choppy" I mean that there's a delay between when I click to drag a window and when I see it actually start to move, for instance, and that I have to wait a second when switching between desktops for the cube to start spinning), and I'd like to figure out how to make it smoother if I can. I've noticed that glxinfo tells me that direct rendering is not enabled, but I don't know why, as I have the latest nvidia driver (beta 1.0.9625) installed. If not having direct rendering would make XGL choppy, does anyone know how to enable it?

Otherwise, I'm posting my xorg.conf file in the hopes that someone might be able to tell me what I can do to make XGL smoother. XGL effects are incredible, but they're making my system so choppy that it's hard to use. I've tried minimizing the settings in compiz, which made things better but not great. Unless my hardware just can't handle it well (which I don't think should be the case, since I've run plenty of graphics-intense games in Windows on the same card without a problem), I don't understand what's making XGL so slow and choppy. If anyone can help, I would appreciate it greatly.

# To disable the XKEYBOARD extension, uncomment XkbDisable.

#        Option        "XkbDisable"

# To customise the XKB settings to suit your keyboard, modify the

# lines below (which are the defaults).  For example, for a non-U.S.

# keyboard, you will probably want to use:

#        Option        "XkbModel"        "pc102"

# If you have a US Microsoft Natural keyboard, you can use:

#        Option        "XkbModel"        "microsoft"

#

# Then to change the language, change the Layout setting.

# For example, a german layout can be obtained with:

#        Option        "XkbLayout"        "de"

# or:

#        Option        "XkbLayout"        "de"

#        Option        "XkbVariant"        "nodeadkeys"

#

# If you'd like to switch the positions of your capslock and

# control keys, use:

#        Option        "XkbOptions"        "ctrl:swapcaps"

# Or if you just want both to be control, use:
