Why do games lag in Unity and not in Unity 2D?

Question

Ubuntu 12.04: All games lag in Unity, but in Unity 2D games don't lag. Does anyone have a solution that it don't lag in normal unity?

processor: Intel® Core™2 Duo CPU E8500 @ 3.16GHz × 2

memory: 3,9 GiB

graphics: GeForce GTX 460


Ubuntu 12.04 32-Bit fresh installed (before 11.10 32-Bit all have worked)
driver: NVIDIAs accelerated Video card driver (Version current-updates)

games: neverball, beep, volley brawl (offline)

Under 11.10 all Games worked fine

Possibly you don't have proper drivers for your GeForce GTX 460 or you graphics card is not fully supported, so try to download them from GeForce website.

You can do some performance testing by installing glxgears (sudo apt-get install mesa-utils).

See Bad 3D Performance in Ubuntu 12.04

See this article to check your performance issues

You could also try switching your desktop environment (Unity) to a different one, like KDE or something by installing one of these alternative desktops

sudo apt-get install kubuntu-desktop
sudo apt-get install xubuntu-desktop
sudo apt-get install kde-full
