The Intel onboard video chip is often called "The Graphics
DEcelerator". My home workstation runs Windows not because I like
Windows, but because the graphics chip simply has NO drivers for Linux
that I could find after an extensive search :P
No, matter, though.
As far as optimization is concerned, I found the Metanet Tutorials to be
a source of inspiration, which lead me to optimize my main loop and
collision to the point where my game runs well even on my garbage
workstation :D Still need to check it out on something with cojones.
