I don't think you were actually paying attention to performance while playing. Portal 2 barely challenges hardware that's already getting old. Even at 1920x1200 with max settings. My systems a year and a half old and it rarely hit below 60 fps. They had plenty of overhead to push more into the levels, but obviously chose to restrict things.Skorpyo said:Think of it this way:
If the levels were larger and the loading screens less frequent, your computer would most likely take a shit from the sheer amount of things that would need to be processed at any one time.
