I was just going to start a topic about this.
Honestly, I hope no. I currently can't play any game that uses VAC2, because of some weird OS/firewall problem that is (hopefully) being worked on by valve now. Their tech support has told me that it was forwarded to the developers and should be fixed soon.
I also know that there are vac2 proof cheats now, so I don't really know that there is a point to running vac2. Is cheating that big of a deal on LM that this is a problem? LM is going empty most of the day now, so is there a point in setting up vac2, and making sure that everything works on the server?
It's not like this is a CS server where most of the people seem to be cheating.. cheating in NS doesn't seem to be that big of a deal (Come on, we have a built in wallhack, ffs)
I believe that currently VAC2 is in a beta, where they are trying to get rid of connection problems, so its not actually detecting anything.. this is what my srcds displays on startup
Connection to Steam servers successful.
VAC beta secure mode is activated.
I don't know, I think that the problems dont even make up for what it will provide
