i also explained with the method you want, you want to change an 11 year old design concept, your attempt would completely screw up updating games. compression is for permanent storage, not for permanently changing content. compression via your method wont save any money and money is the only reason someone would consider doing it.Īnd i say that as a 7zip commit dev for a whole decade. I dont really wanna discuss that further, your attempt is nicely meant, but it will cost more in the long run. Originally posted by ☔ wuddih SpNv ✔:screenshot of active steam download would be nice ) i am eager to buy the crap just to upload a screenshot of the real download amount myself but i hate the game too much to throw my money out of the window It would be the same principle with a game and as I said it would save alot on bandwidth, 20GB to 8GB is a huge saving. Think of it like downloading a Zip file, you download it, unzip it and then install it. As for the resources you wouldn't get any errors, it downloads the compressed files to your disk and after that it will un-compress them. As I said before ''The current Steam compression doesn't really save much space'' Please read previous posts before posting. It is possible, you will see games that are 20GB be compressed into 8GB installers. I am talking about downloading like a 5GB or 8GB file, and it will uncompress to its original size like 12GB or 20GB etc. Skyrim is a 12GB download if you have the DLC and the HD Texture Pack, it's a 12GB download and it's around 13GB on disk. my netbooks hdd starts to fart on most steam downloads on the uncompression part, i periodically get busy writing to disk messages all the time on a download. and i still don't believe that skyrim is a 12gb download if it ends up being 12gb on your hdd.Īlso compression and uncompression takes up resources. space is cheap today, bandwidth costs a bit, so it is efficient to save a bit there. the download is compressed to save bandwidth, not to save space. so you basically want to change a 11+ year old and established design concept. Installing a game on steam never required the game to be extracted from single compressed archives.

Some games are just going to be more amenable to compression than others. That said, in general it's highly dependent on what the input data is what compression ratio is available even under theoretically perfect conditions. That's 52.8% of the original size, which is pretty decent. I usually see pretty good ratios, for example GTA3 here is 1319 MB of disk space required, and a 696.5 MB download.
