System specs can be found in XP in Start\All Programs\Accessories\System Tools\System Information
In the system summery line we want
CPU speed which is the 3 to 4 digit number followed by Mhz on the processor line. With this number we need the type of processor which is more than likely on a sticker on the front of the computer and will say something like AMD Athlon or Intel Pentium
Total Physical Memory (often just called memory)
from the components section in display we need
Name
Adaptor ram (not essential but would help)
Driver Version.
for example mine would look like
Processor - AMD Athlon 64 2210 Mhz
Memory - 1024.00 MB
Display - NVidia GeForce 6600, 256mb, Driver Version 6.14.11.9107
as for the launcher go into your freespace directory (the path can be found in the property's if you right click on the game icon then run the launcher icon, there should be a tab that says display this is where the glide option is.
am I right in remembering glide as a holdover from the old Voodoo cards?
