After initial testing in a beta branch, Valve has pushed Trusted mode out to the live version of the game.
Valve had first added a "Trusted Launch" option to the game menu at the end of June in their latest effort to combat cheating in CS:GO. The mode, when enabled, would restrict third-party applications and software from interacting with the CS:GO client unless the drivers had been digitally signed by an Authenticode signature.
Following a trial phase, Trusted Launch has now been rolled out to all players by default. Users that launch the game with incompatible files will be greeted with a warning indicating what file is causing issues.
For players who may experience problems with the latest update, Valve has temporarily created a backward-compatible branch of the game, while those who wish to allow third-party software that is not digitally signed to interact with their game still have the option to launch the game in -untrusted mode at the cost of a reduced trust score and an inability to join VAC-enabled servers.
The complete patch notes can be found below:
[Trusted Mode] – Players now launch CS:GO in Trusted mode by default — While in Trusted mode, third party software will be blocked from interacting with CS:GO — To allow third party software to interact with CS:GO, you can start the game with the –untrusted launch option. Note that in this case your Trust score may be negatively affected. — A backwards compatibility label “220.127.116.11” is temporarily available for players experiencing difficulty launching the latest version of the game. – If you are a third party developer, all of your DLLs that interact with CS:GO must be digitally signed. — If your customers would like to use third party software that is not digitally signed, they can start the game with the –insecure launch option. Note that they will not be able to join VAC servers with this option.
