Do I need to install an older graphic cards driver for my ATi Radeon Mobility 9700? Which version would you recommend me to install and what do I have to consider?
Not sure -- after ditching my last ATI 9xxx card in 2010, I tried to forgot all that mess about new drivers
But I certainly remember that 2008 drivers got some problems which 2005 didn't.
On the other hand, that could be a wrong way -- after all, dedicated server doesn't even link to the 3D code, and you reported it to crash rather than sitting idly and waiting for connection. Right?
