Your Frames Per Second (FPS) in CoD4 can have a huge effect on the general quality of your gameplay. It also directly impacts a varietly of different functions, as discussed below.
- How high and far you can jump (this is the most well-known FPS effect as far as Quake-based games are concerned)
- Rate of Fire (ROF) for automatic weapons
- How long/far you can move silently when not in a silent stance (crouched, ADS'ed, prone)
- The amount of damage you take when falling
- Your ability to "bounce" off objects
- Your maneuverability while in mid-air
It should be noted that, in CoD4 and all other quake-based games, you can only set your FPS limit to an integer division of 1000 (the max FPS allowed).
So, a few example FPS values would be:
- 1000/3=333 FPS
- 1000/4=250 FPS
- 1000/8=125 FPS
And so on... If you set your FPS to anything other than a "valid" value, your real limit will be the value rounded up to the next valid value. Also, the 3 example FPS settings listed are the ones that provide the most advantage in terms of the effects listed above. All other values either have a neglible effect, or have significant downsides. Finally, 333 provides the biggest benefits in most of the categories, particularly in regards to jump height. However, the makers of Promod decided 333 gave too much advantage to those who's computers could reach it and have limited FPS from 40-250.
Height and Distance of Jumps:Edit
As mentioned, this is the most well-known advantage of setting particular FPS values.
