Net code discussion. Rollback confirmed!

Still can’t even login. Are they reserving servers for certain regions or what? (I live in Southeast Asia).

I played battle lounge with my buddy who is in AZ and I’m in MD, and I’m on PS4 and he is on PC, and it was like we were playing in the same room right next to eachother.

Bad connections are bad connections, everyone needs to just stop trying to play the blame game about it being wifi, PS4, PC, etc. Just accept that there will be bad connections and move on to the next match.

Fight a player in Korea? No lag
Fight someone on in Murica? Just fuck my shit up.

Shout outs to all my foreigns

Someone posted a video in the general thread, someone can lag on purpose withalt tab. I’ve notice people warping everywhere and when the game tries to catch up.

Is this true?

Welp… goodbye playing ranked as a PC user (considering it doesn’t matter for me I guess, since I only played 2 ranked matches… and both of them were bad. Battle lounge invites as a “private” lobby were outstanding though.)

For general public? Yea… they deserve better.

Yeah, that vid made a test. Though…I’m still not sold if it’s true or not. Despite watching it.

That’s not what the video showed. It showed that in a scenario that is already lagging for the PC player, alt-tabbing changes something and the other person lags instead, maybe (a comment to the video claims to be the opponent and said that it started lagging for him after the alt-tab). It does not show that alt-tabbing introduces lag.

I’d like to see the same test done in a game where no one is lagging.

Also, I would like see tests where people actually diagnose what causes issues. Are people teleporting around because their connection to Capcom servers are shit? Are the teleporting because they’re playing on PC with shit fps? Are they teleporting because the peer-to-peer connection between the two players is shit? How can one player teleport and the other not teleport? There are many unanswered things here.

You’re not wrong, but fuck,dude.
When I’ve played a huge amount of PC players and every single one is an unstable mess while every 9 out of 10 ps4 connections are fine, I think this is a little something more than just a simple bad connection. People can give me shit and argue all they want. PC matches suck dick for me. That’s all there is to it.

As a PC player, I play mostly PS4 players, and they mostly great. Skip-fests are very rare. My brother is also a PC player and has been complaining about massive amounts of lag against PS4 players… I wonder if this is some sort of port forwarding issue or something that is screwing with cross-platform play.

there is an interesting comment by Mike Z under a recent eventhubs news article about lag issues and PC vs PS4:

a thought I had regarding the PS4 user complaints about matches with PC users. so according to reviews the PS4 version sometimes can’t keep the framerate up. as far as I know though the game doesn’t slow down in online mode but drops frames in this case. so maybe there is an issue there in the implentation of the netcode, that if one machine has a framerate drop it falls behind in regard to time synchronisation and gets all the rollbacks. which would also mean that PC players with not optimal framerates (consistently under 60) would always get all of the rollbacks of online match. of course I don’t know if this actually holds up. but on PC one could easily test this by cranking up their resolution settings until the game doesnt run well anymore and meet up with someone in a lounge to see if rollbacks are occuring and on which side.

another note, I really don’t like that they made cross platform play optional. before you hate on me, hear me out. the idea behind it was to have one big player community not divided by systems. but since it’s optional any online issue will be blamed on the other system. here are the dirty console peasants with their shitty hardware and wlan connection and there are the cheating and lag-switching PC masturbators. even if there is a specific problem regarding crossplay, if capcom fixes it no one will bother and just keep the systems setting limited. as one can see many PS4 user already saying they don’t wanna play with PC users anymore and if you look in steam forums PC users are complaining about the long loading times on PS4 and also just wanna play with their own. great, fuck cross platform. then why was it implemented in the first place?

I still don’t fucking understand why Capcom would insist to use their own shitty netcode instead of licensing GGPO and asking for help on implementation how KI handled it.
You got one relatively cheap guaranteed option for netcode, and one maybe/maybe not garbage option rotting in your basement.
What do you choose?

May have something to do with Cross-platform.

glad someone knowledgeable like mike z finally chimed in on this. if the problem is easily identifiable like that, then it should be fixable. but does capcom care enough to do it?

What game did you all buy because my experience has been completely different. Playing on PC here with all setting on high and have had absolutely no lag and have probably already played around 100 matches with what I consider to probably be the best netcode of all time. I’ve played a solid variety of PC and ps4 players and I can only recall one match were I even noticed any lag (a few teleports). Anyone that’s having consistent lag problems that doesn’t live in the North Pole needs to check their network equipment/ISP. Hell most games that people complain about lag I have no issues and I am very sensitive to input lag.

You all need to take a few steps:

  1. If playing on wifi stop now and plug it in, especially if you live near other people with their own wifi that will cause interference.

  2. Make sure your ISP is whoever is the biggest and most popular in the area (Time Warner Cable, Comcast, etc.) this gives you the most direct connection to the largest pool of people.Cable internet providers typically have the least amount of gaming lag (low pings and jitter) so choose Comcast & Time Warner Cable over At&t. Even Google fiber has higher pings then cable internet right now.

  3. Make sure your router AND modem are modern high end brands/equipment updated to the latest firmware. So don’t use your ISP’s free router/modem combos. Use high end brands such as Asus and Netgear Nighthawks that cost at least $100 and use a modern modem such as a Motorola/Arris sb183 (if on cable). Default settings are fine and these routers are constantly firmware updated for stable low ping gaming. Yes some cheap routers work just as well (as long as they’re not stressed) but it’s hard to identify which precise models for which games.

  4. If on PC make sure all drivers are updated , especially your network card (should be a recent Intel model). If your computer runs like crap and can’t handle the game then lower settings, try a fresh updated Windows 10 install or get a new pc.

  5. Finally, make sure the bandwidth of Internet being used in your home is well under your theoretical maximum from your ISP (the aforementioned high end routers can show you live network usage from all devices). If you have 100mbps internet it’s fine if your girlfriend is streaming Netflix in the other room (aslong as you have a high end router that can handle a large amount of silmultaneous streams). If you have 5-10 Mbps internet it’s probably not a good idea.

Stop blaming Capcom for your own crappy equipment and connections, you have no idea how much harder netcode for fighting games is to get right then a first person shooter. If Microsoft,Apple,Google, Valve, and Blizzard all got together and created the best fighting game netcode scientifically possible half of you would still have lag from your current set ups.

I love this game netcode, it is per
<rollback>

The fuck. the thing it is totally unplayable I get matching times over five minutes and then 2/3 fetures teleporting.
for the record I have 300/30 Mbs connection and ps4 ultra plays perfectly.

The alt-tab doesnt even works and makes things worse.

I quit until it is fixed

Now I’m having an issue where:

Loses a match: works fine

Wins a match: unable to retrieve information from server

Lol

I played cross-platform with a person from Japan today and hardly noticed I was playing online. This netcode is pretty good.

Lol

The one thing a competitive game needs to get right before launch is the netcode. Looks like 2 weeks from the last beta wasn’t enough.

  1. On wired 1Gbps fibre (only my PC is connected to it)
  2. Almost all ISP fibre is leased from the same Opennet company in my country.
  3. Yes, just upgraded in Jan in anticipation to this game
  4. Updated to newest Nvidia drivers for GTX980 1 day before game release
  5. See 1.

If so why am I running into matches like below? I set battle requests to 5 bars only.

You can see well in the video that I’m clearly struggling (Vega) trying to get my moves and hits registered (The rollback even killed my V.trigger lol) while my opponent is happily doing his combos. The netcode is consistent yes, it gives the player who has a delay/weaker connection the priority. That player will experience buttery smooth gameplay and their sad opponent will get rollbacks until it is unplayable.

If your game feels buttery smooth/lag free as if playing offline most of the time, is it the same “smooth, buttery experience” game for your opponent you are playing with? Your opponent might be experiencing rollbacks/teleports while the game takes your side and make your connection the sync standard. The game chooses a side to render smoothly and make the other an absolute hell. It really makes me wonder on some games when I have silky smooth gameplay where I can land 1 frame links consistently… is my opponent struggling like I am in other laggy matches.

It all comes down to the question, as we all are fighting game fans and we would like the match to be on equal ground. How does this netcode make it playing on equal ground which is the core of fighting games? It chooses sides.
