[SOLVED?] OpenGL apps start very slowly..

Edit: After running a system update today and rebooting for a different reason everything seems to work again, guess it was a bad package? Strangely, I'm pretty sure the packages that updated were not related to the problem (Just mpd, ncmpc, wine, and orc). Oh well.

I have an odd problem with OpenGL applications opening very slowly on my laptop. All other applications seem to work fine. My first thought was maybe direct rendering wasn't on, but it is. Oddly even to check that takes a while to run as seen below:

[jamie@JPC ~]$ time glxinfo | grep direct
direct rendering: Yes
    GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access, 

real    1m23.231s
user    1m23.068s
sys    0m0.103s

Strangely once the program actually opens it seems to run fine as evidenced by glxgears:

[jamie@JPC ~]$ glxgears
16753 frames in 5.0 seconds = 3350.586 FPS
17516 frames in 5.0 seconds = 3503.158 FPS
17828 frames in 5.0 seconds = 3565.519 FPS
17751 frames in 5.0 seconds = 3550.056 FPS

I had this problem a few weeks ago as well, but I somehow resolved it with just some tinkering with some conf files. Unfortunately, I can't seem to fix the issue again.

I noticed this in the FAQ, but it doesn't seem to be my issue (Mainly pointing it out to avoid it as a suggestion). http://wiki.archlinux.org/index.php/FAQ … _at_all.21

[root@JPC jamie]# cat /etc/rc.conf | grep HOSTNAME=
HOSTNAME="JPC"
[root@JPC jamie]# cat /etc/hosts | grep 127.0.0.1

My kernel is 2.6.34-ARCH, straight from pacman. My video card, if it helps (Nvidia packages I'm using: nvidia 256.35-1 and nvidia-utils 256.35-4):

My xorg.conf file is generated from nvidia-xconfig with only a few modifications:

And lastly my /var/log/Xorg.0.log file warnings although they seem irrelevant (There were no errors):

[jamie@JPC ~]$ cat /var/log/Xorg.0.log | grep "(WW)"
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[   114.159] (WW) The directory "/usr/share/fonts/OTF/" does not exist.
[   114.159] (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

[   114.159] (WW) Disabling Mouse0
[   114.168] (WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)

On a final note, sorry if any of the stuff I posted is irrelevant, I'm just pretty confused as what the problem could be. If any other info is needed, please let me know. Also, thanks in advance for any help.
