What is VACnet, a deep learning product of CS:GO’s Overwatch?

In 2018, a developer from the CS:GO team kept before the community the algorithm about the game’s Overwatch methodology and functioning. All you got to do is to refer the 2018 version of the Game Developers Conference for exploring some insights regarding the same


Over the years, CS:GO has witnessed an expnential rise in the sea of cheaters and since then been going through a rough patch until they are ultimately caught and proven guilty, all thanks to the game’s VACnet. From various in-game dismays ranging from griefers to hackers with their triggering game plays, VACnet has been playing an instrumental role in evaluating players who are reported for their unnatural approach towards the game.

In a presentation, CSGO developer John McDonald anchored the 2018 GDC where he focused on “Using Deep Learning to Combat Cheating in CSGO.” In the presentation, McDonald revealed to the public about the Developer team who released the “Trust Factor Scenarios” six months prior to its official launch inside the game. He continued,

“What would happen is you would see a thread pop up on the Steam Community Forums where someone would say ‘CSGO is filled with cheaters.” We would go [and find the user’s trust score] and [they’d] be tied to 50 accounts, and 49 of them have bans for cheating.”

This was followed by McDonald explaining about the Trust Factor where the latter won’t stop players from cheating but would instead place them in a “bad sector” which would match-make them among a pool of cheaters. In the due course, this mechanism would bring all the 10 players cheating among each other hence dealing less impact on the legits.

VACnet is another, extra framework that figures out to break down a specific player’s in-game conduct, learning the cheat’s pattern which later results in boycotting a player pool based on these “similar dependencies”. His thought process was to utilize Overwatch decisions as a “pool of information” to prepare what got known as VACnet, Valve’s profound learning hostile to swindle. This underlying initiative proved to be a success when VACnet was released to pass judgment on cases all alone as CSGO’s designers centered its AI hypothesis around CSGO’s most evident cheats.


McDonald added about these “unpretentious” cheats stay hard to unravel, yet in building VACnet, Valve chose to target aimbots first since they present themselves at explicit, effectively determinable focuses during rounds of CS:GO: when you’re shooting. This permitted Valve to manufacture a framework that caught the adjustments in pitch (Y-axis) and yaw (X-axis)— degree estimations from a player’s point of view.

This expanding about Trusted Mode’s lock down of CSGO, could in the end bring about a cleaner game in general and may represent the wonky matchmaking a few players have found as of late.
