Valve might launch an updated version of the VAC anti-cheat for CS2 in the coming days. This was reported by data miner Maxim "Gabe Follower" Poletayev. He shared his observations on YouTube.
Gabe Follower's report is based on talks with cheat developers, so take this information with a grain of salt. According to them, the developers tested the updated VAC 3.0 throughout the whole of January and were satisfied with the results.
The developers have been regularly enabling and disabling different anti-cheat modules. It could last for a week or a few hours. The duration [of anti-cheat tests] was random, likely to confuse the cheat coders. <...> Last month, they enabled all the modules at once. According to my information, the results of their work were extremely positive. As soon as a user enables any [cheat] function for one round, VACnet bot joins the server and checks the following actions. It feels that the bot joins the client side, too, as affected users have a strong lag and FPS loss at this moment. If the player continues to act suspiciously, he gets kicked from a server and gets a 24-hour ban, which significantly decreases the Trust Factor. When such a player continues to play, he competes in a pool with other cheaters.
The updated version of VAC was announced by Valve in the second half of 2024. The developers didn't provide any details but only mentioned that it was in the works. On January 24, the developers announced second season of Premier Matchmaking. Gabe Follower assumed it would be a perfect moment to launch VAC 3.0.
