3D acceleration problems only in specific applications

Since I installed Arch Linux, I never managed to get some 3D applications to work correctly, although I know my laptop can handle them. To be more precise, stuff like Celestia, Eternal Lands, Flight Gears have abysmal performance (with about one frame produced per 2-3 s, whereas Warzone 2100 is quite smooth. World of Goo is also fast, but perhaps it does not require any acceleration to get there.

Recently I was flabbergasted to see that Runescape, a browser based RPG with a 3D arena was actually quite fluid in my firefox. So I really have the impression that something is very wrong on the software side of things (SDL?), but I'm not sure where to start to look. Any suggestions?

Edit

I installed enemy-territory, and it's extremely fluid, no problems at all. This issue really concerns a (large) subset of applications

What drivers and hardware are you using? What kernel version? Please also include /var/log/Xorg.0.log, xorg.conf (if you have one), dmesg, and glxinfo.

Re: 3D acceleration problems only in specific applications

First of all, I would like to mention that Glest, MegaGlest and Nexuiz are also GPU accelerated.

$ lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X700 (PCIE)

Kernel : 2.6.34

I installed
xf86-video-ati-6.13.1-1
libgl-7.8.2-1 
ati-dri-7.8.2-1
mesa-7.8.2-1
xorg-input-drivers
xorg

Dmesg
/var/log/Xorg.0.log
glxinfo

I don't have a xorg.conf, just

$ ls /etc/X11/xorg.conf.d/
10-evdev.conf  10-quirks.conf  10-synaptics.conf  50-fpit.conf  keyboard.conf
