This is not actually true. The human eye can indeed see more than 30 FPS. When it comes to TV a speed of about 24 (or so, depending on NTS or PAL) was used because of the display of a TV. The screen resolution of a TV set is very low and the refresh rate of each dot (pixel) is very slow. The result is blurring. This blurring results in fooling the eye into thinking that the images on the TV are moving as one frame is blurred into the next. As a result of the slow refresh rate of a TV set no more than 30 FPS would be needed to simulate smooth motion.
This is not the case with computer monitors. They have much faster refresh rates and higher resolutions. There is less "blurring" (due to the refresh rates) and thus the human eye can see a lot more FPS than on a TV. As a result, most games aim for at least 60+ FPS.
To cap FPS Creator to around 30 is very wrong. If there is to be any upward cap then it should be at 60+. Frankly, they should allow the game designer to set the cap (if any).
Quote: "What I am wondering is when the Source Code is released, what happens when you "uncap" it. More than likely they reason they may have capped it is for timing issues during game play. By setting it at a number, all multiplayer, single player will run at a specific rate."
No. FPS only affects how many frames are being displayed on your monitor. The game engine should use some other timing mechanism for the actual game stuff (i.e. running, firing weapons, etc).
In any caes, my main concern is the overall speed of FPS Creator. I think the tool has potential, but if I am going to get only 17 FPS in a level with very little detail then there seem to be a problem that needs to be addressed.
