Valve has warned Counter-Strike 2 players that AMD’s latest graphics driver could get them banned. The problem lies in AMD’s Anti-Lag+ feature, which triggers the Valve Anti-Cheat (VAC) system, duping it into mistaking the driver’s low-latency mode for cheating.
The problem lies in Anti-Lag+ intercepting and redirecting Dynamic Link Library (DLL) functions. VAC views DLL reroutes as cheats (in other cases, they often are), which could lead to getting booted from Counter-Strike 2.
A Reddit thread about the issue claims “many players” have reported receiving VAC bans from using the latest AMD driver (23.10.1). “It seems that VAC is banning everyone BUT the cheaters,” quipped u/Volfong in the thread. “Can confirm I got banned today and Anti-Lag+ was turned on,” wrote u/trkemrasr. “They better reverse this shit quickly.”
Valve plans to do just that. “Once AMD ships an update we can do the work of identifying affected users and reversing their ban,” the publisher posted on X (formerly Twitter).
AMD’s latest driver has made their “Anti-Lag/+” feature available for CS2, which is implemented by detouring engine dll functions.
If you are an AMD customer and play CS2, DO NOT ENABLE ANTI-LAG/+; any tampering with CS code will result in a VAC ban.

Until the problem is resolved, Valve recommends turning off Anti-Lag+ in the graphics card settings. If you haven’t changed the default, you can disable Anti-Lag+ with the hotkey of Alt+L. You can double-check the shortcut’s setting by opening AMD Radeon Software, clicking on the gear icon and choosing Hotkeys from the sub-menu. Selecting the existing hotkey for Anti-Lag+ allows you to customize it.
Engadget has contacted AMD for comment and will update this article if we hear back.
Counter-Strike 2 launched in September after months of hype. The update, which replaced Counter-Strike: Global Offensive on Steam, adds upgraded graphics and maps alongside more realistic smoke. The game uses Valve’s Source 2 engine for improved lighting, clearer textures and updated geometry. You’ll need a somewhat modern Windows machine to play it as Valve says it has no plans to bring the sequel to macOS or older PCs.
