Q: What is a TAS?
A: TAS stands for Tool-Assisted Speedrun. In short, TAS runs are perfected runs which could never be achieved by a human.
Q: How is a TAS made?
A: In TAS runs, the person making the TAS uses a "movement recorder", which lets them make segments, rewind them, replay them, and perfect them down to the tick. This allows the TASer to make a perfect or near-perfect run which could not be achieved by a human.
TASers also lower the host_timescale setting, which makes the game play in slow-motion. This allows them to circumvent human reaction time. (Imagine it like this: https://gfycat.com/CarefulBasicAmeric...)
Strafe hacks are also used. Most TASes made in recent times use a 1-tick autostrafer, which strafes 66 times per second. Since the player is going in a straight line, they can get from point A to point B much faster than with normal strafes, as going in a straight path is always quicker than going in a curved path.
Q: But isn't that cheating?
A: The point of TASes is to show what a perfect, super-human run would look like. In order to do this, TASers use whatever tools they have at their disposal. These are NOT meant to be compared with a human-achieved run.
Q: Why don't you strafe when travelling in a straight line?
A: This is where the aforementioned 1-tick autostrafer comes in. You can't see it, but the player is, in fact, strafing 66 times per second.
