without more details i can only guess, try a more recent kernel version (via backports if neccessary) and if that doesn't help my guess would be that the 3D game is using some feature your hardware or libraries don't know about or haven't implemented correctly. without knowing more details we're just kinda shooting in the dark here. do you have a built in graphics card or are you using some other graphics card? if so, make sure you are using the most recent drivers for that too. if the program or OS is crashing in some manner a coredump may help. still i would try the kernel update first, 2nd check graphics drivers, then see where that gets you. songbird
