Edit: Since setting Appearance -> Visual Effects up to a stunning "Normal", I now get ~35 FPS in glxgears right after login, with nothing else running :(

I'm getting terrible graphics performance in NeverWinter Nights (native with SoU+HotU+CEP2) on my Eee PC 1005HAB. Even with all graphics settings (including the "advanced" ones) at minimum I get about 2-10 FPS, depending on the scene. Firefox is really sluggish as well - Changing tabs often takes a second, scrolling is laggy, and typing this I notice the delay between pressing keys and seeing the text on screen. The rest of the OS is running OK, although general performance seems to be even worse than my old Eee PC 900.

glxgears gives about 60 FPS, which is apparently as it should be (synchronized with the monitor refresh rate).

Bugs like Launchpad #252094 and the instructions for Reverting the Jaunty Xorg intel driver to 2.4 are old enough that I'm afraid following the instructions would render the system unusable.

Are there any tips for improving graphics performance on this system that are still relevant for 10.10?
