 === Lag and lookdown ===
-First of all, what does lookdown actually do?<ref name="lag and lookdown" /> Well, it makes it so that less things are rendered on screen, thus increasing the framerate. However, if we dig a bit deeper, and look at how this affects in-game values in memory, we'll see that it mainly affects the value that tells the game how many 1/60th ticks (i.e. "frames") that passed since the last update.

 To figure out how many frames have passed, the game checks the value of the N64 CPU cycle counter.

-Lag is caused by anything which makes more work for Goldeneye to do before it completes a game tick, so the causes are much more than just "what's on screen". However, levels are divided into [[rooms]], objects are marked as being '[[on-screen]]' and generally what is on screen has a much bigger effect on lag than just how long the rendering takes.

 Beyond broad ideas, not a great deal is known about the relative size of various causes. But that's not to say that the player base hasn't becoming pretty skilled at reducing lag, including through some rather [[Runway#Hut grenade|subtle strats]].

 * Weapon switching / pausing - this creates a lag spike as the new object is spawned in, and the size of the lag spike is specific to the weapon. The exact cause is unknown but could relate to fetching the files from the ROM and decompressing them. This seems insufficient to explain the size of the lag spike though.
 * Bringing things on screen for the first time (new rooms / guards who have been off-screen)
 * Guards, particularly when loaded and active (moving or shooting)

-Lag refers to game lag in [[Goldeneye 007]].
+Lag is wherever the game frame rate drops, and that's quite often in [[Goldeneye]].
-== Overview ==
+Its main effects are [[#Lag and speed|slower forward movement]] and [[Warping|warps]]. It directly determines the fire rate of automatic weapons, which is a bottleneck for areas of many levels such as [[Dam|Dam SA]] and [[Train]]. A large part of [[Overall Control of Bond|OCB]] is coping with lag, particularly avoiding stucks in heavy lag, and experienced players are very sensitive to it.
