this is pdifferent from the p2p client, which actually does wait for both players inputs. it rly does depend on who you play and this is the stupidest off-topicness ever. Let's get back on topic instead of arguing which one is better bc they are both pretty good.

This is wrong. 2DF uses rollbacks and prediction as well. That's the only way to have a 0 input delay. And from what I understand, where GGPO's smoothing feature has to be manually adjusted, 2DFs occurs automatically based on initial ping.

GGPO bugs:

• Unable to connect to opponent, must double challenge so 2 emulator windows are open.
• Unable to accept a challenge because it says they aren't a registered user. They must relogin.
• Unable to spectate a match because it says the match is not available. Must reenter the room.
• No notification when challenged declined so you have to wait and eventually cancel your challenge.
• After cancelling a challenge and starting a game with someone else, the person you previously challenged is still able to accept which opens a new game window, messing up your current match.
• Bursts of lag (sounds like a fast motor), occuring mainly when spectators join.
• After logging in, people can't accept your challenge because it says you aren't registered. Then if you try to chat, it accuses you of spamming.
• Still able to get challenged by multiple people even though you are already in a game.

GGPO has a great network algorithm and I'm very happy it will be used in up coming games, but 2DF is the same if not better in many situations (I never get the motor boat effect, and im able to play people in europe and brazil even though I live in the US. On GGPO playing people from those same locations, it stutters so much it's annoying), and the GGPO client just feels so half assed. I don't understand that claim of "Its just p2p". So is GGPO. They both use very similar techniques to mask lag and provide 0 input delays, which is why most people can't tell the difference. Damdai has said it is based on nfba p2p, which he optimized and tailored for 2DF. I used to use nfba, but I get consistently better connections with 2DF, so he mustve changed something.

Btw, I only heard about capcom possibly licensing ggpo, which is great seeing as hyper fighting was absolute garbage. Wheres your source for the arcsys games?

2df is nothing but p2p wrapped in a place to meet up with people. if you already have those people, nFBA + p2p does the same stuff. GGPO and 2df aren't even in the same ballpark really

You're right about them not being in the same ballpark. GGPO doesn't even come close.
Your comments on 2DF being nothing more than a p2p wrapper is very ignorant and quite funny to those who have actually used 2DF, and is actually more in line with that GGPO is.

Lets review the undisputable facts.

1. Most people can't tell the difference between GGPO and 2DF connection wise. And for those that do, it is split down the middle which one they prefer.
2. GGPO has an insane amount of bugs, 2DF has none.
3. 2DF has tons more games and features, stat tracking and ranking, and top notch website integration. GGPO does not.

I dont get how you put up with all the crap that you have to go through to get a game going in GGPO, especially when theres crazy better software out there. I couldn't take it anymore so I tried 2DF. Having played both, 2DF is superior in every way. You can stay a GGPO fan boy all you want while the rest of us move over to 2DF, you're only hurting yourself.
