I actually like it
My halo loads up in 2 seconds instead of 15.
Not sure that I like this...
Downloading whilst in game will lead players with poor connections to lag even more.
Caching large amounts of data can sometimes lead to memory problems.
The 'Chat Customisation' doesn't work properly on Radeon graphics cards.
If most servers are running HAC2, and you're not, then you're effectively blocked from joining them servers. Can you imagine a noob to the game knowing that they need to download this software?! ....So less players on servers.
AND
The name is Halo Anticheat, yet "Despite the name, there's no anticheat in this build." .
It downloads before joining, if you don't have the map.
So it shouldn't lag your game.
It doesn't cache large amounts, only the hash keys for the .map files so they don't have to be calculated and loaded every time you start halo.
Haven't tested the chat customize thing. but so far chat works fine for me + it fixes chat lag after alt tabing.
I don't think it will block HAC2 users, I think that will be an option for the server admins.
Anti cheat will be added to this later on, its only a early beta remember.
