I'm sorry but this launcher is horrible. I had it running for over 3 hours when updating the game to the latest version and it was still on 6% when I got back. Then I downloaded the newest game version manually and it took me like 5 minutes to do what this launcher struggled for 3 hours to get 6% done... Unless I've missed something, there's 0 reason to download and use this launcher
The speed of the launcher is based on location to server (us based), internet connection, and cpu speed (for file hashing). I can install cor with the launcher in a little under 4 minutes. File integrity I can do in 1m55s Every time I test I get at least 200mb/s out of my 400mb internet.
The majority of the first 30% is all files bundled with the installer, the main downloading comes ~34% when it has to download a little over 4GB of the actual game files. Either you have a very weak cpu, or the install is stuck in which case send me the log and I can take a look at it.
Possibly. Not everyone has had poor download speeds when they are on the opposite side of the world from the server. I do have a GPU version of the patcher I am testing which should do the file hashing faster on people who have dedicated gpu's. That will at least speed up part of the process. Looking into compression as well so the download size is smaller, although I'm not sure how much more rpa files can be compressed.
