SuperTuxKart 0.9 recently released, is a free 3D kart racing game, with many tracks and with a focus on having fun over realism. You can play with up to 4 friends on one PC, racing against each other or just trying to beat the computer; single-player mode is also available.
The main new features since version 0.8.1 is the switch from Irrlicht to Antarctica a new graphical engine. OpenGL 3 is now required, and the minimum supported requirements include an intel HD 3000 integrated GPU. Quite a bit of work has also been done to implement the online multiplayer (networking), including features like logging in and managing an online account, and online achievements. However, don’t get too excited just now because the actual networked multiplayer gameplay is not yet ready to use (this will come in a future version).
Some issues found with supporting older hardware (e.g. automatic resizing of large textures did not work as expected), and work was done to make SuperTuxKart run on older hardware. But as mentioned above, you do need a more recent graphics card and driver. Especially if you have a more powerful graphics card, adjust the video settings till you find one that offers the best combination of looks and frame rate.
