AMD has made an oversight in implementing their new technology that poses a significant issue for Counter Strike 2 players who have opted to utilize AMD’s AntiLag+. Recently, AMD introduced a new 23.10.1 driver allowing players to access this technology in the game. However, it has now been confirmed that utilizing this technology can lead to a ban.

Despite Counter Strike 2 being launched just this month, it has already earned attention from all major GPU manufacturers, each offering dedicated graphics drivers. AMD’s most recent release introduced Anti-Lag+, an exclusive feature for the Radeon RX 7000 series, aimed at enhancing responsiveness by optimizing frame alignment within the game’s code.

It has been discovered that manipulating DLL functions with AMD’s technology could result in a VAC ban. Valve may consider lifting the bans only when AMD provides an update for this technology. Until that happens, it is recommended not to enable this technology in the game.

The Anti-Lag+ technology is an improved tech that only works on Radeon RX 7000 series and RDNA3 based products. The tech is available in multiple games but Counter Strike 2 is the only that has reported problems with implementation. The game also supports NVIDIA Reflex technology, but Unlike Anti-Lag+ which works on a driver level, Reflex is incorporated into the game itself.

Tweet from @CounterStrike:

"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.

Once AMD ships an update we can do the work of identifying affected users and reversing their ban. @AMD"

So actively altering game code can be misconstrued as trying to cheat. Well consider me fucking shocked.

Things like reshade and controller api modifcations redirect dll functions. The line is kind of vague about the specifics.

Should people on steamdeck ironically be banned for how proton changes how the DX11 is read and converts it to vulkan?

it's just converting the call that the game make to vulkan, it's different, it don't touch game code at all

Its not exactly, its a dll conversion. You overtake the dll the game uses and replace it with a different library. Same idea with reshade. You bypass the dll given by the game to use your own.

Possibly not since Proton is Valve's thingy, but who knows.

And yet use of actual cheats doesn't result in VAC bans, and the game is in just as bad of a state as CS:GO, with most old cheats being easily ported over. Good fucking job...

Not even purely just a CS/Valve issue, which is the worst part. Anything that runs BattlEye struggles with rampant unpunished cheating, and yet they successfully ban anyone running legit systems, or software that has nothing to do with the game. Somehow it's only getting worse, because a bunch of new games are introducing Ring0 anticheats, that have access to way too much information, but still fail to do what they're designed to

still fail to do what they’re designed to

they were designed to create chinese botnet, and they will

«anti-cheat» is the same as «anti-terror» — a gift-paper wrapper

It's of course easier to ban something that modifies game files without hiding it, than it is to ban something that tries its very best to hide its very existence.

[–] [email protected] 12 points 2 years ago

It does results in bans of course but they sadly don't catch up with cheaters fast enough.... Or in some cases is difficult to catch on without the crazy anticheats we have seen complains about.

AMD when injecting code into a game triggers the anticheat

suprised

[–] [email protected] 24 points 2 years ago (1 children)

That's fucked, imagine having no idea, enabling it and being banned from a game you've been playing for years because of something your graphics card manufacturer suggested.

[–] [email protected] 6 points 2 years ago

valve said they would undo the bans based on this once amd gets rid of their anti lag software for the game

The game also supports NVIDIA Reflex technology, but Unlike Anti-Lag+ which works on a driver level, Reflex is incorporated into the game itself.

This shows how Nvidia's size and money allow it to improve its market position without necessarily having better tech. They may sign deals with game developers to implement Nvidia-exclusive features rather than have to tamper with DLLs and such.

[–] [email protected] 8 points 2 years ago (1 children)

Or...you know... they actually provide a SDK for devs to implement it (unli'e AMD).

[–] [email protected] 6 points 2 years ago* (last edited 2 years ago)

Not sure what you mean, obviously they must provide some bindings for developers to actually use their product.

But it's not enough to offer a solution — you need to get people to use it. Doing it this way means Nvidia has to go out and convince studios to spend the effort, provide assistance if necessary, etc — which plays to its strengths as market leader, because it doesn't require their product to be better, it "just" requires more employees and business contacts.

AMD, being smaller, instead goes for a riskier lower-level approach that needs less contact with developers, hopefully side-stepping the need to extend resources to drive adoption, because games get the feature "for free".

[–] [email protected] 3 points 2 years ago

That's probably for the best.

[–] [email protected] 1 points 2 years ago (1 children)

Surely Valve is reversing these? I'd be pretty pissed.

[–] [email protected] 28 points 2 years ago (1 children)

Read the last line of the quoted tweet.

[–] [email protected] 8 points 2 years ago

It appears that I have made a mistake.
