Here's the something to keep in mind...
I posted this before and some half baked moron told me I didn't know what I was talking about. He said I was too technical. That technicality happens to come into logical play.
The human eye only see\thinks so fast. It can not and will not detect FPS above 40, in fact it may be lower, but it has limits.
You can't tell 100 fps from 40 fps, unless you have a metering device to tell you so. Had AH never shown you FPS, you would never know how slow you are until you actually drop below 25 fps. The picture then starts to degrade.
The moron told me TV, VCR and games are different. BS, frame rate is frame rate and a VCR is like 25-30 FPS, I can't remember which.
I'm going to go back to research this again to get exact numbers, but these are in the ball park. ;-)
