Does anybody know or have an idea just how much bandwidth starcraft 2 might use. I wanted to know because i know allot of us have bandwidth caps. Maybe if i hasn't been tested yet we could us WoW as a bench mark because the games are similar and are form the same company.

Very little, in 1v1 matches <4KB/s i think. I was using a proxy capped at 32kbps and played with no lag. Brood War also uses like 2-3 KB/s.

probably not so little as <4kb/s, but it's RTS, shouldn't take much bandwidth that it becomes a real concern.

you can't deduct the bandwidth usage from WoW because the two games are quite different. I don't think it'll use really that much Bandwidth though

Those estimates are higher then reality. 4kb/s is a lot of data for an rts game to be transmitting. Even during raids and BG's wow will rarely use more then that. I watched my transfer during a game of nexus wars where we were maxed out, and it wasn't breaking 2kb/s down. So i would imagine it would be less during a 1v1.

If you are truly concerned with how much data you're using, you can download a program called net limiter monitor. This displays all processes, and shows the transfer rate. It also logs this data, so you can look back to see how much you used over a period of time and so forth.

As far as I remember - when playing dota consistantly I did a little testing, and I believe the total usage over an hour long game was roughly 5-8mb. This was of course with me hosting the game, thus I believe it was a little more than a normal peer connecting to me.

I guess you can take that with a grain of salt comparing it to sc2.

For playing: a negligible amount of data, even for people with fairly tight bandwidth limitations.

For downloading maps: A few megabytes at most, unless you download a ton of huge custom map projects. Most ladder maps should be less than a few megabytes, at least.

For downloading patches: This one varies tremendously. If it's just a balance patch, it shouldn't be too large. If it's a "content" patch that adds new music / art assets, it could be very large. Some WoW patches are almost a gigabyte (in fact this is pretty common, since most WoW patches are content patches that add new zones, music, monsters, art assets, gear etc., which takes up a lot of size). One of the SC2 beta patches was 900mb iirc, and I think another one was 600mb. I'd expect not to see a patch this large anytime after release, though, since most of the music/art should ship with the game.



Disclaimer: These are just my rough estimates, and are not based on any hard data. Bandwidth is virtually unlimited for me, and since I have an extremely fast connection capable of downloading hundreds of gigabytes a day with no cap, I don't worry about it.

If you want accurate data and want to split hairs down to differences of a few megabytes, I'd suggest running a program that monitors the network usage of SC2.exe while you play a few ladder games, and check the map file sizes yourself. The freeware version of NetLimiter, for example, has a Network monitor that can keep track of transfer rates like this.

Pretty sure that watching a 10 minute long youtube video in 720p would equal hours of Starcraft 2 ladder in terms of bandwidth.

256 KBPS DSL or better SHOULD provide smooth latency for SC2, however, that is of course if your ISP does not throttle.

No, he's not talking about lag/speed, but how much bandwidth does SC2 eat. Because we all know that stupid Rogers has a bandwidth limit.

But yea, I would guess very little as well.

i think his concern is how much bandwidth he's going to use over a period of time, not the speed of his connection. Some people have caps for that i've heard :D anyway sc2 shouldn't use up that much bandwidth but don't take my word for it i have 24mbps DSL reaching 16 something.

24mbps? How much do you guys pay? I bet it definitely costs way less than what we pay for an 8mbps here in Canada...You guys are so lucky that you don't have a bandwidth limit! *jealous*

I'm pretty sure a replay stores ALL data which is transferred to you during the course of a game.
I might be wrong however, but I don't think it's something you'll have to worry about, unless, as mentioned earlier you play lots of custom maps.

I think it's probably a fair guess to assume that the size of the replay roughly corresponds to the amount of data transferred over the length of the game. In BW if you had a replay that was let's say 100KB and was a 4-player game that lasted 20 minutes, I think it makes sense to have 100KB transferred over those 20 minutes. Maybe add in some keepalive packets to the Battle.net server on top of that, as well as other extremely negligible bandwidth impacts.

RTS games (and most games, really) use a very small amount of actual data, but what matters the most is latency: That is, how long it takes data to move from place to place.

The biggest pipe in the world doesn't matter for games if the latency is too high.

I guess its plausible that it takes such a low amount, since both users don't need to transfer much data between each other (I wonder if chat takes more than the actual game).

Your average 30min game of SC2 has a replay size of <200kb.
All the information needed for the game to take place can be contained within a replay file.
I think you can take his word for it given this fact and his statement.
