nVidia has posted a warning on their Linux forum here (http://www.nvnews.net/vbulletin/showthread.php?t=178460) about a serious issue with the GeForce 6, 7, and 8800 GTS/GTX cards, K/Ubuntu 12.04, and their latest 295.40 driver. The 295.40 driver is the default installation in Ubuntu 12.04 as I write this.
Until a fix is released, you can run Precise in Ubuntu 2D mode as is, then uninstall the 295.40 driver and install the 295.33 driver which can be downloaded here (ftp://download.nvidia.com/XFree86/Linux-x86_64/295.33/). Be sure to follow the instructions in the readme located in the 295.33 download directory.
I'm successfully running Precise in 3D mode with the 295.33 driver, getting ~8000 fps on my 8800 GTS card. I troubleshot 12.04 for about 7 hours before discovering the nVidia driver issue. nVidia is actively working a fix.
Someone may want to make this post sticky until the fix is released and incorporated into 12.04.
