My alienware m18x came with the latest graphic drivers provided by Dell, however, I have an issue with this driver version: stuttering when mouse goes on the upper right corner of a game I play often, 'heroes of newerth' - they say the solution is simple, update to either 10.1 or 11.6 driver version. The problem is that my laptop won't accept any driver but the one provided by dell, I completely uninstalled the dell one and tried to install the one provided by amd, unsuccessfully, since it install but does not work. Anybody have any idea? Thank you.
