Is VAC also disabled in other games?

Yup.
But its bad idea use this disabler for other games.
 
Why that?
Because this is VAC disabler for dota. And developer create this disabler only for dota.
I'm not a coder, im designer.. but i think for other games need some improves for disabler.
 
it's not bad but you can't play them it will kick you with vac authentication error.
