the netcode in both arma and arma 2/OA is the worst i've ever seen... its genuinely the laggiest and least smooth online experience ever.
whenever you are in a vehicle with other people that vehicle jerks along, literally everyone who i've spoken to online admits its just armas shocking netcode. players warping about is a regular thing. it doesnt matter if you are playing on a server with a low ping, you still get lag. im convinced its the main reason arma 2s PVP scene is so dead, and im not even sure if the forthcoming PR mod will be popular due to erratic player movement/lag issues.
with regard to walker, he thinks the game is perfect... so he's never going to admit to its many failings !
