For me it's Motorhead , released 7 years ago 
It runs at >350fps with 8x Supersampling AA/16xAF at 1280*1024
I remember being blown away by the graphics in the beginning but now they are just ugly and very little detail, when I look at such a game it makes me think how fast development in the computer industry and videocards has been.
What is your oldest game you still play?
