1. 0:00In the latest Neverlose update
2. 0:01extrapolation was added
3. 0:03In this video, we'll break down what it is
4. 0:05why it's needed
5. 0:06how extrapolation works in practice
6. 0:08and why this feature inevitably has its limits
7. 0:11Enjoy!
8. 0:12Let's start with the basics
9. 0:13with definitions
10. 0:14because this is exactly where a lot of players still get confused
11. 0:18There are concepts like backtrack
12. 0:20selftrack
13. 0:21interpolation, and extrapolation
14. 0:23Backtrack is relatively straightforward
15. 0:25This feature lets you work with the enemy's past position and shoot at it
16. 0:29within reasonable limits, of course
17. 0:31Selftrack, in turn, lets you shoot from a position where the local player used to be earlier
18. 0:36And finally
19. 0:37interpolation and extrapolation
20. 0:39These are the two terms players mix up the most
21. 0:42Interpolation is the creation of additional records between real ones
22. 0:46It's typically used for the visual side of things
23. 0:49to smooth out jitter and make movement look more fluid
24. 0:51Extrapolation is an attempt to predict a player's future position
25. 0:55based on their previous movements
26. 0:57What does this give you in practice?
27. 0:59The aimbot can shoot at a point where the enemy hasn't appeared yet for the client
28. 1:03but already makes sense for the server
29. 1:05Because of this, you get the feeling that you're shooting with noticeably lower ping
30. 1:09Which means you gain a tangible advantage
31. 1:11Let's look at a clear demonstration
32. 1:13Our ping is 60
33. 1:14We assume a camping position with extrapolation off
34. 1:18Now we turn extrapolation on
35. 1:20in the exact same situation
36. 1:22The advantage is visible to the naked eye
37. 1:27First and foremost, the aimbot has to be able to predict the enemy's movement
38. 1:31If the enemy starts moving, you can try to figure out what speed they'll reach and where they'll end up a few ticks from now
39. 1:37Our cheat, both in CS:GO and CS2
40. 1:39is constantly collecting snapshots
41. 1:42per-tick records of the player's state
42. 1:44These records are needed for backtrack
43. 1:46that is, for working with the model's past positions
44. 1:48But their usefulness doesn't end there
45. 1:50this same history can also be used for extrapolation
46. 1:54By analyzing these records
47. 1:56the cheat can figure out the enemy's current state
48. 1:58whether they're standing still
49. 2:00accelerating
50. 2:01jumping
51. 2:01or decelerating
52. 2:02But the cheat can't know for sure how long this state will last
53. 2:06That's exactly why patterns have to be built
54. 2:08a set of the most likely behavior variants
55. 2:11Next
56. 2:12you need to use these patterns to figure out not just what the player is doing right now
57. 2:16but what they'll most likely do in the next moment
58. 2:18And this is where the most important step begins
59. 2:21you can't get it wrong about how far into the future you're predicting
60. 2:25If you want to land your shots
61. 2:27extrapolation can't go beyond server reality
62. 2:29Otherwise the shot will go to a place where the player isn't on the server yet
63. 2:33Simply put, you don't shoot into the "furthest possible" future
64. 2:37but into the position that already makes sense for the server
65. 2:40This is precisely why this mechanic creates the feeling of lower ping
66. 2:43the aimbot is shooting at the model that's closer to server reality
67. 2:47If your ping is low
68. 2:48even at high values the cheat won't predict further than the position that already makes sense for the server
69. 2:53But at high ping, the number of ticks really does matter
70. 2:56because the possible prediction window becomes noticeably wider
71. 2:59Now about the most likely misconception
72. 3:02It's a mistake to assume that extrapolation will always make the cheat hit
73. 3:06That's impossible by definition
74. 3:07You can't see the future
75. 3:09You can only predict it, and hope the prediction turns out to be correct
76. 3:12The enemy can deliberately break the prediction logic
77. 3:15randomize their movement, sharply change direction
78. 3:18or change anti-aim angles
79. 3:20The negative factor of randomness can't be fully eliminated
80. 3:23So it's important to remember that the more ticks the aimbot tries to predict
81. 3:27the higher the chance that external factors will interfere
82. 3:30and ultimately lead to a miss
83. 3:33The idea of extrapolation itself looks fairly clear
84. 3:36But making such a feature genuinely accurate
85. 3:39that's significantly harder
86. 3:40There are several reasons why extrapolation wasn't added for a long time
87. 3:44First
88. 3:45no one wanted to interfere with the established meta too early
89. 3:48Second
90. 3:49this feature spawned too many side problems and edge cases
91. 3:52For example, what players usually call "shooting at birdies"
92. 3:56that is, into thin air
93. 3:57That said
94. 3:58it's important to understand that extrapolation is a natural step in the evolution of rage functionality
95. 4:03The industry was bound to arrive at this mechanic one way or another
96. 4:07More than that
97. 4:08it's not just an "interesting feature"
98. 4:09but a genuinely useful tool in practice
99. 4:12It's needed for higher-quality autosto
100. 4:14for playing on high ping
101. 4:16for Zeus
102. 4:16and overall for pushing rage functionality
103. 4:19closer to its maximum effective state
104. 4:23For high-ping players the game will become both easier and harder at the same time
105. 4:28Easier, because they'll start playing as if their latency were noticeably lower
106. 4:32Harder, because their opponents get the same tool
107. 4:34That said, this feature still won't bring full fairness
108. 4:37Low-ping players can use extrapolation too
109. 4:40just over a smaller number of ticks
110. 4:42And the smaller the prediction window
111. 4:44the higher the resulting accuracy
112. 4:45Which means low-ping players will get more accurate extrapolation
113. 4:49The main takeaway from this video
114. 4:50extrapolation is a strong feature that gives a noticeable advantage in-game
115. 4:55Like any mechanic, it has its limits
116. 4:57but that doesn't make its practical value any smaller
117. 5:00Extrapolation noticeably changes the usual gameplay
118. 5:03and makes the game against those who use it competently significantly harder
119. 5:07Thank you for watching!
