While I don't know the netcode itself, this info from maverick adds another piece to my puzzle of how it works. It obviously fails at predicting positions when there is packet loss but is still using quite a lot of cpu to calculate that warping. I've also noticed that putting a load on a server (like going to F10 and zoom around on a server, everything keeping the cpu busy) will cause warping on the clients. Also if the client alt-tabs, takes a screenshot or whatever, keeps dcs (the client) from sending packets. So whenever the server has to deal with packet loss it fails and seems to put load on the server, the more load the less good the server can handle everything and the more warping you see. I got no clue what kind of code they implemented that causes behaviour like this, but this is the behaviour I observed. The only thing the game would need to do in simple speaking is: "i got no packet, lets guess the next position the airplane might be and dont bother much more until the next packet". I'm still missing pieces of the puzzle to understand the current algorythm, like does the server calculate physics at all, or is it all done client side (which would make prediction less easy, but reduce cpu-load on the server). Also, if it was as simple as I described it would be relatively easy to fix/the fact it wasnt fixed yet indicates its not that simple. In any case I would be surprised if these observations are very far from the truth.

I agree with Maverick on this, his solution sounds very plausible and seems to work (the 104th server indeed does not have this kind of warping problems). I would like to strongly encourage you to at least give this technique a try!

I hear you Maverick and i agree wholeheartedly. But I also agree with greg, no scripting = no blueflag. The only one who can help is in fact c0ff when he finally finishes the new netcode and dedicated server (c0ff please take as much time as you need, but do it as fast as possible ;) I understand how hard the task is you're assigned to). Seriously, the scripting and respawning and whatever blueflag does in terms of game-development is not overly complicated and must not be the reason that causes lag, because if it was, we would be doomed to dogfight from A to B like on most other servers, which is not a very attractive option in my opinion. The scripting engine has soo many goodies left for us that we haven't even scratched, and I'm really looking forward to help creating interesting scripted missions that add more dynamics to flying DCS. In 2-3 years this is going to be awesome! Unfortunately right now its quite a pita.

Theres two blades on the sword. One side is that DCS is not very good at handling packet loss, and packet loss usually increases with the ping. High ping itself is not the major problem. The scripts itself are very lightweight and optimized, xcom, ciribob and greg did a great job there, unfortunately theres a couple of gliches in the DCS-code that starts bringing up problems with time and playercount. A lot of features have already been taken out to increase stability (like hover-pickup of crates). Keep in mind that there have been major improvements (new 3D engine first and foremost) in DCS which naturally introduce new bugs, and there just wasn't enough time for ED to fix those, and ED is not a 250+ man company like some major gamestudios.

Me too. With a proper prediction code and and better packet-loss handling the MP experience should skyrocket. Unfortunately the requirements of a flight-sim netcode are a bit more complicated than "the ordinary fps netcode", so I have a good understanding why it takes a while (I spent 5 years coding games before my twenties, also did a lot of research on netcode implementations, but this was more than 10 years ago)

Server has crashed once again 5 minutes into the game and is frozen at the same servertime (visible, but not joinable)

ahh at least I'm not the only one with that problem. Oznerol, keep in mind it's not the servers fault, the scripting is not very heavy and the guys spent a lot of effort optimizing it. The code of DCS is just not yet able to handle it without freaking out. I'm positive this will change (hopefully) soon. A lot of things have been improved already in the past 6 months. We'll have to give ED some time. I have to admit though it hurts really bad sometimes, blueflag is just too good, and round 5 is the best blueflag ever!

Oh boy, tonight for me was the worst lag I've ever experienced in DCS. I got disconnected twice in the air, then killed myself once by stupidity, and this is how I lost my last live. i was getting seriously claustrophobic, and I have absolutely no explanation what was going on: I was chasing an F15 about to get a solution when this happened. I had absolutely no more control about the plane. Edit: I got no idea why the video doesnt work, heres the link: https://youtu.be/w48wF8IRvtw

me too, like the past rounds, ВАРЯГ has done an amazing job (in fact all of the guys you named), and I would be sad to see him joining blue-side. I also cannot think of any reason that would make him joining blue-side make sense ...

seems the server crashed again. we waited for 30 minutes till we could finally get into fighters to fight off the blue strikers that already took off from sochi, when we got on station the game froze for all of us. Server is displayed up and full with all the dropped players on it (including me, according to the app)

everything is closed after restart, except minvody, sochi and gudauta plus a couple of farps ...

yes, choppers are now bigger than ever!

I have a mission in the works which borrows the basic gameplay principle of blueflag (and a bunch of code) on a much smaller scale (less distance between the objectives, all all objectives are in the mountains around inguri valley). It will be up for testing when blueflag round 5 is finished. It will be called "The Kaukasus Offensive". I agree, have observed this many times. 2.5hrs seems to be the magic time.

The script thinks slot "MV_red_SU27 33 Minerlye Vody" is a reserved slot, although theres no clan-tag attached.

Well, I wasnt warping when you gunned me, but you rubberbanded away twice when I managed to get on your six the sortie after when I was about to take revenge and got two sweet 73 solutions, lost you on the second one cause you extended but the game kept me in a turning fight. One glitch and you were gone :huh: then you got me, one mistake too much. Well whatever, its not your fault. The game will eventually improve and the time will come when I'm experienced enough to get you. only started fighters after watching the 99th guys grilling red su27s from a huey in round 3, I'm learning as fast as I can ;) everytime you get me a little more :joystick::pilotfly:

fair point :megalol:

thank you! :)

Server is down. Once again shortly after choppers brought fuel.

server is down :cry:

+1, i too think this would solve many problems at once. I've had a red guy with a short non-word name attack me as well, it was shortly before restart on the last patrol and I managed to evade his shots, but it still was a pita ... I think a swing with the banhammer would be appropriate!

Pick one up, they don't cost much and it will turn your gameplay-experience around. You will all of the sudden find yourself in a team of fighters strikers and choppers working together. Once you've tasted that, you wont turn back!

I'm 100% sure I posted this this morning, no idea why it's disappeared? :O This might help you on the way: http://forums.eagle.ru/showthread.php?t=150315 Take the tactics part with a grain of salt, but the systems are very well explained!

Sound like you did not join TS, and maybe even that 27 that shot you was not on teamspeak. Like already pointed out, a mission of this scale needs solit flight planning - OF ALL PARTIES. A lone airplane cannot do really much, but if you coordinate with a team it makes all the difference, just look at how far blue came this round, all with a sincerely impressive teamwork-display! In fact the red team is in a big need of capable strikers that are ready for duty once air-superiority is achieved. We had air-superiority over the Maykop-Minvody farp yesterday for more than 45 minutes, including choppers with troops in the vincinity but the only strikes I noticed was two (2) anti-radiationmissiles. The blue side eventually set up kub, and how my airsuperiority ended can be seen one post above when maverick showed up ... So you're very welcome to try again and please make sure you join TS!

Why did I know this would end up here?! :D
