Valve improved network code in CS2: New level of precision and responsiveness

In CS2, as in previous versions, the accuracy of network code is critical to a comfortable game experience. Valve has taken this a step further by introducing the Sub-tick system, which greatly improves synchronization between player actions and the server. This system solves the problem with lag and unsynchronization, which was an issue for many CS2 players.

Unlike traditional approaches, Sub-tick tracks player actions with high accuracy, regardless of what tickrate is used on the server.

Sub-tick is a technology that captures every player action, such as a move or shot, at the exact moment it occurs. Unlike conventional 64Hz tickrate servers where the data is updated at regular intervals, Sub-tick allows the server to record events with much higher accuracy. This results in players now being able to experience a more accurate response from the game and a reduction in unsynchronization.

How does this affect players?

The Sub-tick innovation improves game interaction, especially for those who have experienced lags and lack of accuracy while playing the game. It will have a particularly positive impact on those who play competitive modes where every detail matters. Players will be able to react more accurately to their opponents’ actions, which increases the overall fairness and competitiveness of matches.

This system also has a significant impact on cyber sports tournaments, where every millisecond counts. Thanks to Sub-tick, improved synchronization between player and server actions makes the game fairer and more predictable. It also makes practicing easier, as players can use the official CS2 servers without having to resort to third-party platforms with higher tickers.

What to expect in the future ?

While Sub-tick is already improving the gaming experience, Valve is still working on optimizing and improving CS2’s networking code. We can expect more updates in the future to improve the stability of the game and create a more comfortable experience for players in both casual matches and cybersport tournaments.

Sub-tick technology is an important step towards improving network stability and accuracy in CS2, which has already brought positive results and continues to improve gameplay.
