Anyone Noticed How Inaccurate Calculated Download Size is For Games Nowadays?
Anyone noticed when you download a game, the calculated size before the download is often double the actual size of the game? I noticed this with every single game I downloaded onto a new hard drive, someone please tell me I’m not just going insane.

The files are compressed. They are uncompressed after download when installing to save bandwidth.

Of course it’s a given that they are compressed, nonetheless, you would still assume that is taken into account in the estimate, compressed or not.

Steam requires x2 or x3 the space to download, unpack and install a game. Once fully installed the space required to do this is freed up leaving you with the space taken only by the game.

Other:

Store pages are maintained by the dev, pub and all information is provided by them and if a game has received updates, additional content etc, the game size will increase but unless they update the info on the store page you will always see what the size they initially provided.

That is not how compression works. There are 2 points where data on your computer gets compressed if you own and SSD, in firmware; then in the filesystem. It's not worth guessing.

Yeah erm, no.

It doesn't work like that. Compression isn't a fixed ratio by any means. It varies WILDLY.

And as others have said, Steam works by having files compressed AND encrypted. You should always allow up to THREE TIMES the total file size anyway for it to download and have swap space to sort stuff.

I've tried to raise this point a couple times & no-one seems to get it.

I bought a game recently that said you need 30GB. I had 20GB of internet left.
Could I d/l, couldn't I? Could I get most of it, some of it?

Turned out the d/l was 10GB. There is no way to know that. It very easy to know that. :headbash:
No it isn't, none of that changes what we've said already.

The fact is with a game it changes anyway, so right from the off you have the problem of updates and things being fluid.

The fact that games are also compressed and encrypted alos then compounds it further.

Could it be done? Maybve, but that doesn't change the inherenet problems.

So it seems like the problem is you have limited Internet and often don't know how large the game files are to download because the only information provided is estimates on disk space usage either on the store or the download manager.

I could see how that could be frustrating. And it surely doesn't seem like your data caps are much of a concern for Valve or developers.

Yeah this still remains a THEM problem.

NObody shoudl agree to an online focused service with poor internet. That's entirely on them.

Possibly. For some people it's a rock and hard place situation. When I was growing up in rural northern MI there were two options, 56k and 33k. Certainly as the user you have to accept the realities of the circumstances. I couldn't scream at game companies to make games run better on dialup, the problem was the infrastructure and re-purposing primitive systems to let computers communicate. Ultimately I moved a few hundred miles south and that problem went away, but being twenty and having no attachments made that easier. I can't say moving across the state for better Internet is a terribly great solution for everyone.

In this case the user wanting to know how much data they're actually gonna need to use isn't wholly unreasonable. Even if it doesn't appear to be a concern for Valve and developers.

And if the user doesn't really have any other options, claiming the circumstances are "on them" doesn't read that well to me.

At any rate these systems are still evolving and so are user needs and expectations. Our OP is just experiencing some of the symptoms of those growing pains.

What "download estimate"? There is no estimate. Before installing the game, it lists the size the game has after installing and then on the download page it lists the size of the download. That's not an estimate.

The only estimate is for the unpacking and installing process. But that has no bearing on the download size.

To be fair, Valve could simply add the download size to that little pop-up you get before installing, where it lists how much disk space is required for the installed game size.
Brian9824 2022 年 5 月 1 日 上午 11:33 
Yeah i was gonna say valve displays INSTALLED size, not download size.

A fair point. Never thought of that.

Absolutely.

But the bottom line is that it still falls upon the end user to get a connection or not complain when it doesn't work ewell. That's just aprt of your obligations.

Sucks, but it's how it is.

True, compression does vary widely, between different files. My thinking is that the devs could at least test (to some degree) what compression would do to the size of the game. Not on the store page of course, that’s where you worry about the physical size of the game in storage, but before you’ve downloaded it. If you don’t have enough space on your computer, steam will tell you. If you do however, for those with an internet cap or for those with limited time that want to know how long the game will take (the steam estimate is calculated before compression and is almost always incredibly inaccurate) it would be nice to know how big the game is bandwidth wise, rather than how much storage it will take up once it’s done, without waiting for a download to start. It’s not a big deal, but it’s a nice quality of life change I would like to see.

Apart from all the above your filesystem is another factor here. Depending on the way the file system is set up files can actually vary in physical size. For example block size, this also determines the minimal file size of any file on your system.
