Hardware inflicted lag

One of the most common causes of lack is also the one most easily identified: lack of sufficient hardware resources, i.e. insufficient free memory, a slow/outdated graphics card or lack of free disk space.

On Linux, run these commands in a terminal window to find out about your hardware:

Available memory:

LANG=C free -m | awk '/^-\/\+ buffers\/cache:/ { print $NF}'

CPU:

awk -F: '/^model name/ { print $2 }' /proc/cpuinfo | head -n1

Video hardware:

lspci -kmmnnv | grep -B1 -A7 '^Class:\WVGA'

On Windows, press and hold down the windows key, then press SysRQ key (top right of keyboard), then release both. You should get a screen which displays basic information on your computer.

Make sure that your computer provides the minimum hardware requirements of MegaGlest.
